Description

one

The equipotent applies to automation and numerical engineering, in particular to devices for classifying signals of objects, and can be used to classify acoustic and geophysical signals, more specifically, to determine maximum values of several close to normal distributions of numbers transmitted over a single communication channel, for example , at recognition of codes of depth of geophysical signals.

The purpose of the invention is to increase the reliability of the classification of object signals.

Figure 1 presents the block diagram of the device; 2 shows a pulse distribution circuit; FIG. 3 shows temporary D1 grams, which remove the operation of the control unit.

The device contains a control unit 1, an OR element 2, an AND 3 element, a first 4 and a second 5 comparators, a pulse distributor 6, a register 7, a first counter 8, a second counter 9 ;, a memory block 10, and signal selectors 11 including a counter 12, the first 1 and second 14 triggers, the element OR 15 shaper 16 pulses and the element And 17,

The distributor 6 pulses contains a counter 18 and a decoder 19.

In addition, the device contains the first 20 and second 21 inputs.

The device works as follows.

By the signal from output 20, unit 1, by the first output, generates a command, according to which the input signal (code) to be classified, from input 21 is written to register 7 and at the same time counters 8, 9 and 12 are set to the zero state. Output code of the distributor 6 decrypted with the decoder, selects the first signal selector 11 (upper in FIG. T), and through block 10 connects to the input of the comparator 5 the smallest reference value.

The pulses arriving at the counting input of counter 8 from the third output of block 1 change the state of counter 8, the output code of which goes simultaneously to blocks 4 and 5. When the output code of counter 8 is equal to the value of the reference, the output of block 10 is triggered by a comparator 5, the output pulse which increases by еди95D262

The contents of the distributor counter 6, which sets the next reference value at the output of block 10 and is decrypted in the distributor 5, select the second signal selector 11. When the counter code 8 reaches the new value of the standard, the comparator 5 re-operates, the output pulse of which increases by

10 unit the contents of the distributor counter 6, the output code of the counter connects to the input of the comparator 5 the third value of the standard and selects the third selector 11, etc.

5 When the counter code 8 is equal to the code stored in register 7, a comparator 4 is triggered, the output pulse of which is fed to the building input of the decoder of the distribution box bis output of its output through the OR element 15 increases the contents of the counter 12, the output pulse simultaneously enters the second input block 1 and stops it,

25 When subsequent signals arrive at input 18, the order of operation of the device repeats each time, after a predetermined number of times, unit 1 switches the device to Dos30 mode by setting the triggers 13 and 14 to the zero state by applying a pulse from the fourth output,

From the second output of block 1, the counting pulses arrive at the first input.

35 of the element I 3, which is open at the second input by the resolving potential from the overflow output of the counter 9, made inverse. Pulses from the output of the element 3 through the elements

® OR 15 simultaneously arrive at the counters 12 of all the selectors 11. When the counter 12 of one of the selectors 11 overflows, the flip-flop 13. switches to the opposite state ,.

 In addition, the overflow pulse through the open element And 17 sets the trigger 14 c. A single state, the potential from the output of which goes to the output of the device,

0 To prohibit signal codes that have a large weight in the histogram, but are not the maximum in a separate distribution, prohibiting the potential from the inverse output of the trigger 13 of the selected selector, 11 enters the element And 17 of two adjacent selectors 11, thereby prohibiting the passage of an overflow pulse from

counter 12, to a further circuit. Thus, only the output of those selectors 11 passes a signal, the number of which is equal to the code of maximum values of individual independent distributions of codes of numbers transmitted over one communication channel. The shapers 16 generate a short pulse, which, through the element OR 2, enters the counter 9, and the pulses on the shaper 16 are formed with a certain delay and the delay time for all the shapers is different. This is done in order to eliminate the ambiguity of the situation at the output of the element OR 2 in the case of simultaneous formation of pulses from different selectors 11,

When determining the predetermined number of individual maximum values, the counter 9 overflows and the signal from its inverse overflow output closes the And 3 element at the second input, stopping the Completion of the device.
