A disadvantage of the converter is the low compression ratio of the information.

Also known is an adaptive analog-to-digital converter containing a pulse generator, a code transfer unit, the first input of which is connected to the output of the first OR element, and the second inputs - to the discharge outputs of the first reversible counter, the first input of which is connected to the first input of the second OR element and terminal Start two

A disadvantage of the known converter is that it implements the principle of adaptive information compression using a zero-order extrapolator, therefore, it has a low compression ratio, especially for converting processes that have areas with a parameter change that is close to linear. Such processes include the vertical structure of temperature changes in the seas and oceans with a clearly pronounced linear portion of the thermocline (temperature jump layer). Since a sharp change in temperature is observed in this area, sometimes reaching 1.5 C / m, the known transducer forms many unnecessary counts practically with a change in depth within the error of the depth gauge, which complicates the restoration of the structure and collects a large amount of unnecessary information.

The purpose of the invention is to increase the information content of the device.

As reversible counters 1 and 2, microcircuits 564IE11j can be used as counters 3 and 5 - microcircuits 564IE10; as a trigger 17, a trigger, for example, a microcircuit 564TP2j as triggers 16, and 18 are counting triggers, for example, a microcircuit 564ТМ2.

The Converter operates as follows.

The signal on bus 31 causes the converter to return to its initial position. In this case, the register 9, the reversible counter 1 and the triggers 16 and 17 are set to O, and in the reverse counter 2 through the OR element 27 is set 1 Analog input signal, previously converted into a pulse frequency signal f (t), is fed from the input bus 30 to the first inputs of register 9 and block 12. Clock pulses with a period t following, coming from the first output of generator 10, to the shift input of register 9, move the information arriving in the form of a sequence of pulses to the information input of register 9. At the output, register pulse sequences and 9 f, (t) is at a zaderzhL

which equals T Nptg, where N is the bone in register 9 bits. A delayed sequence of pulses f (t - T) goes to the third input of block 12, which by synchronization of one sequence with the leading edge, and the other with the falling edge of clock pulses t , coming from the output of the generator 10 to the second input of the block 12, provides for the shift of the pulses of the input sequences coinciding in time, which is necessary for normal operation of the reversible counter 1 with separate inputs. To the counting input of the addition of the reversible counter 1, an input pulse sequence f (t) is fed, and to the input of the Subtraction, a delayed sequence of pulses f j (t is T). The reversing counter 1 integrates

impulses sent to its counting inputs taking into account the sign of the inputs. At the initial moment after the converter starts, the input frequency f (t) pulses are received only at the input.

corresponding to the digital equivalent of the initial value of the measured parameter, where T is the averaging time of the input frequency, equal to the delay time in register 9; f is the average for the time T, the pulse frequency.

After time T to the input. Subtracting the reversible counter 1 from the output of the register 9, the block 12 begins to receive pulses of the delayed sequence, f (t - T). From this point on, the reversing counter 1 begins to integrate the current input frequency increment over time T. The current increment of the number of pulses in counter 1 is equal to tt

The total number of pulses in the counter 1 during the time t from the moment the device is started up is

N, lt) (tl - T (tlt (tH. (31

Thus, at the output of the reversible counter 1, a continuously varying g code is formed (with a discreteness of the low-order unit proportional to the current frequency of the input signal at time t. The generated code N of the initial value of the measured riapaMeTpa enters output terminal 32 as follows. First the impulse of the delayed sequence f (t - t) j, which occurred at the output of the battery 12, sets in position 1 a flip-flop 17, -C the direct output of which receives an enabling signal to the And 21 element. On the leading edge of this signal at the output of the former 19, a pulse is formed, which sets the trigger 18 to the O position, and the leading edge of the pulse at the inverse output of the trigger at the output of the former 20 produces a pulse that opens through the OR element 26 block 15, through which the NP code arrives at the output terminal 32. the inverted output of the trigger 18 also opens element 22, through which the first output of block 12 begins to receive pulses of a delayed frequency f (t - T) passing through the element OR 29 to the fourth input of block 13. Simultaneously from the second output of block 1 2 through the open element I 21 to the first input of block 13 pulses of the input frequency f (t) pass. The trigger 16 is set by the Start signal to the O position, respectively, the block 13 is in the forward position, in which the input frequency pulses fj ({t) are fed to the Addition input, and the delayed frequency pulses are T) to the input Subtraction of the reversible counter 2. At the outputs counter 2, a code 4N. (t) is formed, which is proportional to the current increment of the frequency of the input signal. When the input signal increment code reaches the specified aperture code set in block 11, i.e. at uN) (t) NQ, the digital comparator 6 is triggered. The first pulse from its output t means the end of the formation of the time interval T, in which the current increment of the input signal reaches a given aperture. T is determined from the expression N, aN (t1.J4f (t) a-Tf; (tK 99 from and inversely proportional to the average rate of change of the input signal fx (t) during time T,. Counter 3 and digital comparator 7 form the control The first divider of the reference frequency F, coming from the generator output 10, is divided by a factor equal to a given aperture N. When lc, i NUMBER of pulses in the counter, 3 values of the code of a given aperture N, coming from the output of block 11, the digital comparator 7 operates, at the output which produces a pulse, zeroing counter 3, and a new chi starts. l set the number in the counter 3. Therefore, the frequency at the output of the digital comparator 7 is equal to 1. The pulses of this frequency are summed in the counter 4 during the time interval C, since the And 24 element is open from the moment of the occurrence of the first and tulsa of the delayed frequency (t - t) J t when the trigger 18 is set to the O position, before the appearance of the first pulse at the output of the digital comparator 6, which sets the trigger 18 to the position I, at which the AND 24 element is closed and the AND 25 element is opened. In the counter 4, the digital equivalent of the N-interval is formed. timeN. v - “. f; w is inversely proportional to the rate of change of the input signal. Counter 5 and digital comparator 8 also form the control of the divider of the reference frequency F, coming from the output of the pulse generator to the counting input of counter 5 through the open element I 25, by the division factor N coming from the outputs of the bits of counter 4. At the output of the digital comparator 8 at the moment when a code reaches a number code in counter 5, a counter in a 4 N counter produces pulses whose frequency is M4) fx (i.e., is proportional to the average rate of change of the input frequency and is equal to the increment of the input frequency per delay T. Frequency fj does not change until the control code N – j at the counter outputs 4 changes. The frequency f is output from the digital comparator 8 to the input of the element OR 28. Since the pulses of the frequency F are shifted in the generator 10 relative to the pulses f, the frequency pulses f formed from the frequency pulses Fp never coincide in time with the input f pulses (t and delayed f (t - T). frequencies synchronized in block 12 by frequency pulses fp. Therefore, pulses f and f (t - t), which enter its inputs, are mixed at the OR element 28, and a frequency 5h ff, (t - T) is produced at its output at the moment when the first pulse t, signifying the end of the formation of a digital equivalent of the time interval T (interpolation interval). The trigger 18 switches to position 1 and the signal from its direct output opens an AND 23 element, through which the frequency f begins to arrive at the input of the OR element 29, and from its output - to the fourth input of the switching unit 13, to the first input of which the input frequency f (t). The reverse counter 2 produces the number of pulses Cho, 140.1 (, .W- (tK, i) ,.) Tdf (t) t where is the deviation of the current rate of change of the input signal from the rate of change of the signal on the HFiTerminal interpolation T,. At the moment when the number (t) in the counter 2 reaches the magnitude of the given aperture N, the digital co-driver 6 is triggered, the second pulse t (4Q (Fig. 8) at the output of which generates a signal of the first substance; real signal. Through this signal 27, the reversible counter 2 is set to the initial position, and the trigger 18 is in the O position. In this case, on the leading edge of the signal at the inverse output of the trigger 18 at the output of the former 20, a pulse is generated, which opens the block 15 through the OR 26 and opens the reversible counter 1 on the weekend A code N is transmitted to terminal 32 (tcoi of the input signal corresponding to the moment of SSR 1 of the first significant reference. At the same time, a pulse from the output of shaper 20 corresponding to t (-Q passes to output glue y 36 to obtain an auxiliary signal (for example, time or depth ) the measured function corresponding to the moment of essential counting, and also the counter D is zeroed. At the same time, the element 25 is removed, and the resolution signal is given on the elements 24 and the digital equivalent of the next interval begins in counter 4 time i, inversely proportional to the average rate of change of the input signal over time T, referred to the time interval after the first significant reference. In this cinema counter 2, during this time, the digital equivalent of the current input signal increment relative to the measured function value at time tj- is formed. When the current increment code at the reversing counter 2 has a specified aperture code N on the spin of digital comparator 6, the signal t ..,, at which the control trigger 18 changes its position, the counting of pulses in counter A stops and the formation of the frequency fj at the output of the digital comparator 8 begins. Then the cycle repeats. For each pulse tj.Q from the output of the digital comparator, which characterizes the moment of existence13

In this case, the digital equivalents of the measured and reference signals are polled. For each pulse t,.., The time interval V: is formed, the code of which is inversely proportional to the average rate of change of the input signal.

la on the time interval

Thus, the converter allows to realize the first-order interpolation-extrapolating algorithm. At time intervals V (FIG. 8, interpolation is performed by a straight segment, the angle of inclination of which depends on time f and a given aperture (interpolation segment) at time intervals from t to t. The first order of the measured function is extrapolated to , while the current rate of change of the signal does not deviate from the extrapolated rate of change, specified in the interpolation interval, T-, by the value of the specified aperture (extrapolation interval). At the recovery-measured function with a given aperture, a linear int Generation between significant samples. With an alternating increment of the input signal, the input signal may repeatedly intersect the linear section of the extrapolation. At the same time, the number of pulses in counter 2 decreases to zero and then changes the sign of the deviation. Kodo numbers in counter 2 uses block 14, the signal at the output of which, at the time the number in counter 2 decreases to zero, trigger 16 switches to position j at which block 13 switches to inverse switch. In this case, the high frequency sequence of pulses begins to be fed to the input. Addition 5 a is smaller to the input. Subtracting the reverse counter 2. Therefore, on the codes of the bits of the reverse counter 2, the modulus code of the current input increment deviation from the input signal increment on the corresponding interpolation segment is always formed . The deviation sign is determined by the signals at the outputs of the trigger 16, nocTynasfflUHNOi at the output terminals 35 and 36, the Signal t of zero times the number of pulses in

counter 2 may be removed from the output of block 14 to bus 34 and carry additional information about the process of changing the function. 5 At these moments, it is possible through the element -Shy 27 and block 15 of code transfer to poll the code of the current signal at the outputs of the reversible counter 1.

The 1D digital comparator and digital aperture setting unit (Fig. 2) work in the following way.

The switch sets the code N. During the operation of the reversible counter 2, at the moment the NIN is left at its outputs, a code equal to the code N, a control pulse appears at the output of the digital comparator 6. On the timeline

(FIG. 8) the moments of coincidence of the sneakers Q at the output of the reversible counter 2 N (t) HHHdN j (t) and block 11 correspond to the time t.,.,

l C01 K2 sog works similarly

digital comparator 7. When the code reaches the J1 code at the outputs of the counter 3 code set by block 11J, a pulse is formed at the output of the comparator 7, and the counter 3 is set to position O.

“Block 12 (Fig. 3) works as follows.

. When the pulse f (t - T) is touched, the C-input trigger 39 switches to position 1 and the D-input of the trigger 40 is supplied 1. Then, on arrival from the generator 10, the clock pulse f to the C-input of the trigger 40 and the input element I -NE 43 flip-flop 40 is also paired to position 1. At the IS-43 element code, O is generated. At the end of the clock pulse, 1 appears at the output of AND-HE element 43, which includes a one-shot on the OR-46 elements 47 and 47, the capacitor 49 and the resistor 51. Impulse - formed by a single vibrator. switches the triggers 39 and 40 to the position O. Thus, upon receipt of the W-pulse at the C input of the trigger 39 and

0, at the time of arrival of the clock pulse, a pulse is formed on the forward code of the trigger 40.

Scheme assembled on triggers 37 and 38 and AND-NOT elements 42 and OR-NOT

S 44 and 45, the capacitor 48 and the resistor 50, works similarly. But since the clock pulses controlling this circuit, from the output

15

AND-NE elements 41 are inverse with respect to clock pulses f, two outputs of the device (direct output of trigger 38 and direct output of trigger 40) generate pulses that are time-shifted relative to each other, not overlapping one another, with a duration equal to the duration of clock pulses. pulses

The timing diagram (Fig. 4) shows the case of simultaneous arrival of input pulses at the inputs of block 12.

Elok 13 (fig. 5) works as follows.

With zero setting of the trigger 16, i.e. in the case when at its inverse output and, therefore, at the second inputs of the elements And 53 and 55 there is 1, the frequency of the pulses from the output of the element And 21 through the elements And 52 and IGSh 56 enters the summing input of the reversing counter 2, and the frequency from the output the element OR 29 through the elements AND 55 and OR 57 - the input of the counter 2 is subtracted. With a single installation of the trigger 16, i.e. in the case when at its direct output, and hence at the second inputs of the elements And 53 and 5A there is 1, the frequency of the pulses from the output of the element And 21 through the elements And 54 and OR 57 is fed to the subtracting input of the reversing counter 2, and the frequency of the pulses from the output of the element OR 29 through the elements AND 53 and OR 56 - to the summing input of counter 2. Thus, the device allows to connect to the summing or subtracting inputs of the reversible counter 2 frequencies of pulses from the output of elements 21 and OR 29.

Block 14 (Fig. 6) operates in such a way that in the case of the appearance of reversing digits 98996 at the outputs

it has a counter 2 logical O, the output of block 14. a control pulse appears.

Block 15 (Fig. 7) operates in such a way that upon receipt of a control pulse from the output of the ITM element 26 to the second inputs of the elements I 58-61, the output of block 15 shows the SI code corresponding to the code

About the outputs of the bits of the reversible counter 1.

By introducing three pulse counters, two digital comparators, a control trigger, a pulse forwarder, and AND and OR elements with their connections, the device implements an algorithm for interpolating extrapolating analysis of the first order of variability of the measured function. This makes it possible to estimate the average value of the rate of change of the input signal, which determines the strategic direction of the signal change, in contrast to

5 from the estimate of the instantaneous value of the derivative that can be given. false direction in pulsations, noise, and accidental signal spikes.

0

Due to the implementation of the first-order interpolation-extrapolation algorithm in comparison with the known algorithm, it is possible to restore the measured function

5 piecewise linear approximating function with a given accuracy and a significantly smaller number of significant samples, especially for functions with linear segments large

0 values, which are vertical structures of change in water temperature, in the seas and oceans. This makes it possible to significantly increase the information content of the device due to the additional compression of the collected information.
