Description

The invention relates to automation and computer technology and can be used in control and telemetry systems when it is required to form a discrete signal with the hyperbolic law of changing its time or frequency components.

The purpose of the invention is to enhance the functionality by generating a signal, which is a hyperbolic function of time or frequency.

FIG. 1 shows a functional diagram of the proposed generator; in fig. 2 - timing diagrams explaining the principle of generator operation in the signal generation mode, which is a hyperbolic function of time; in fig. 3 - the same, explaining the principle of generator operation in the mode of signal formation, which is a hyperbolic function of frequency.

The generator contains two counters 1 and 2, block 3 of code comparison, decoder 4, register 5, generator 6 pulses of the reference frequency, element NOT 7, four elements AND 8-11, element 2И-OR 12, multivibrator 13, two elements 14 and 15 delays, two generators 16 and 17 single pulses, the first and second triggers 18 and 19, the initial setup input 20, the mode setting input 21, the synchronization input 22, the start input 23, the reset input 24 and the output 25 of the hyperbolic signal generator.

The hyperbolic signal generator operates in one of two modes: the output signal generation mode of the hyperbolic function of time or the output signal generation mode of the hyperbolic frequency function.

In the first mode, the generator operates as follows. After the power is turned on, the input potential 21 is supplied with a zero potential (Fig. 26) and the clock pulse (Fig. 2a) is input to the input 22. Then, a short pulse is applied to the input 24 of the trigger 19, as well as the counters 1 and 2, the register 5, and the trigger 18 (in Fig. 1, only the zeroing circuit of the trigger 19 is shown). Set at the input 20 code number But. The same code decrypts the decoder 4. Then a start command (Fig. 2c) is sent to the device terminal 23.

On the leading edge of this signal generated by the waiting multivibrator 13, the pulse is allowed to rewrite the code But from register 5 to counter 2. Then, on the trailing edge of the clock pulse, generator 16 is triggered, the output of which tilts trigger 19, allowing the output of pulses from the generator 6.

The generator 17 of single pulses (GOI) forms a single pulse constructed by the first pulse of generator 6 arriving at it. input after the differential from “1 to“ About the sync pulse at input 22.

The impulse from the output of GOI 17 through element 12 is fed to the counting input of counter 2, where it is summed with the number Ho recorded in it earlier (Fig. 2e).

At the same time, the first pulse of the generator 6 is fed to the summing input of counter 1 and through the delay element 15 to the sync inputs of block 3 and decoder 4. Thus, since the trigger 19 triggers, the counter 2 counts the sync pulses input to 22 through GOI 17 and the element 12, and the counter 1 — generator pulses 6. Until the arrival of the counter 1 input but pulses at the output of the trigger 18, the output 25 has a high signal level (Fig. 2k). After the input of the counter 1 But of the pulses at the input of the decoder 4, through the time m, determined by element 15 (Fig. 2h), a pulse appears, which through element 8 enters the installation input of the trigger 18

0 and overturns it (Fig. 2k). Then, the (1) pulse arrives at the input of counter 1, i.e., now the moment of counter codes 1 and 2 equals, resulting in the output of block 3 (by a synchronizing pulse from the output of an element

5 15) a pulse arrives for setting one state of trigger 18 (Fig. 2k) and through delay element 14 (the delay time of which in total with the time delay of element 15 is shorter than the period of the generator 6 impulses,) to reset

0 to the zero state of counter 1 (Fig. 2i). Further, if for a time equal to (But + 1) periods of pulse generator 6, no clock pulse arrives at input 22, the same signal will be generated again at the output of trigger 19 and the device will not differ from that described (starting from the moment when a start signal is applied to its input 23).

If during this time a sync pulse arrives at the device input 22, then the code 2 (Fig. 2e) will contain a code of the number (Ho- | -2), and after re-fixing the But code in counter 1 with the decoder 4, the pulse from the output of the latter passes through element 8, sets trigger 18 to the zero state. Then, two more pulses from the output of the generator 6 (Fig. 2g) are sent to the input of counter 1, and the block 3 detects the equality of the codes of counters 1 and 2. As a result, the output of block 3 has a pulse (Fig. 2i), which sets

0 the trigger 18 is in the one state and through the element 14 will reset the counter 1.

Further, until the moment of overflow of the counters 1 and 2, the generator works in the same way as described. At the moment of overflow of the counters 1 and 2, which is detected by the element 11, the output of the block 3 is alternately received a pulse, which sets the trigger 18 into one state. The signal produced by element 11 is supplied

to the second triggering input of the standby multivibrator 13, which, on the falling edge of the pulse generated by it, provides a copy of the code But from register 5 to counter 2. Next, the generator works in the same way as described (starting from the moment when the start signal is applied to its input 23).

Thus, in the first mode, at the output of the trigger 18, a signal of the hyperbolic function of time is formed when it is presented in the pulmonary form. In this case, the duty cycle of the output signal pulses is determined by the hyperbolic dependence (with a stepwise approximation of the hyperbola by 2 sections, where p is the discharge counter of 1 and 2).

In the second mode, the generator operates as follows. After the power is turned on, a high potential is applied to the input 21 (Fig. 36) and to the input 22 - clock pulses (Fig. 3a). Then, a short pulse is applied to the input 24 of the trigger 19, as well as the counters 1 and 2, the register 5 and the trigger 18 (in Fig. 1, only the zeroing circuit of the trigger 19 is shown). A code of the number 000 ... 01 is set at the input 20: a unit in the least significant bit. Then a start signal (Fig. Sv) is fed to the input 23 of the device. By the difference from the logical unit to the zero level at the input 23, the waiting multivibrator 13 generates a pulse, in. the falling edge of which is allowed is the census of the code OB ... 01 from register 5 to counter 2. Then, on the falling edge of the clock, GOI 16 is triggered, the output of which tilts trigger 19, allowing pulses to be output from the generator 6 pulses (FIG. H). The first pulse of the generator 6 is fed to the summing input of counter 1 and through the delay element 15 to the synchro input of unit 3. As a result, counters 1 and 2 fix the equality of the codes by block 3 and a pulse delayed by element 15 appears at its output (Fig. ), which through element 9 enters the counting input of the trigger 18. At the output of the trigger 18, output 25, up to this point there was a high signal level (Fig. Зж), which changed to low with the arrival of the generator 6 pulse at the input of the counter 1. Pulsed by element 14 pulse from unit 3 output returns to zeroing the counter 1 and through the element 2I-OR 12 - to the input of the summation of the counter 2, i.e. it contains the code of the number 000 ... 010. This means that now the equality of the codes of counters 1 and 2 is fixed by block 3 after the arrival of two pulses already from the output of generator 6 (Fig. Ze) after the first operation of block 3 since the device was turned on. As a result, at the output of the trigger 18, Vits has a high potential (Fig. ЗЖ), which is maintained for three periods of the pulse of the generator 6. In the future, until the counters overflow

1 and 2, the operation principle of the RO device of the second mode is preserved. At the time of the first simultaneous overflow of counters 1 and 2, from the output of block 3, 2 pulses will go to the counting input of trigger 18 (2 is an even number), which means that at time of overflow 1 of counters 1 and 2, trigger 18 will appear in one state (like after zeroing when the generator is turned on). Further, the generator works in the same way as described.

t ,,

In this case, in the second mode, at the output of trigger 18, a signal of a hyperbolic frequency function is generated with 2 sections, approximation of the hyperbola.
