SU632063A1 - Pulse train shaper - Google Patents

Description

180, pulse counters 2, 3; trigger element AND 5, element NO 6, block store1 and nporpaiviMbi 7.

Block 7 contains a shift register 8, the outputs of the bits of which are connected to the inputs of the encoder 10 through a group of forcors of short pulses 9.

The device works as follows.

In the initial state, the counter pulse.

2 is reset, and in the counter of i.muls 3 the number A1 is written (in Fig. 2 A1-8) the number of pulses in the first series is necessary, the trigger 4 is in the zero state and the element 5 is closed. With the arrival of (C-A1) pulses from the inverse output of the generator 1, where C is the em. Of pulse counters 2 and

3 (in Fig. 2C 10), an overflow of an hour counter 3, and an overflow pulse through the open element 6 sets the trigger 4B to a single state, allowing the pulse itself to pass from the direct output of the generator 1 through the element 5 on vyho.ch device. The pulses are passed on the output until the pulse counter 2 overflows. The counter overflows through the C and pulses from the inverted output of the generator 1, when the trigger 4 is set to the zero state and the element 5 is closed. Thus, at the output element 5 is formed by a series of A1 pulses. At the same time, the pulse pulse overflow pulse 2 closes element 6 and zeroes the pulse pulse counter 3. The pulse, which can occur as a result of counter resetting the pulse 1, pulse 3, cannot overturn trigger 4, since pulse element 6 is closed. The same pulse shifts the unit in register 8 by one bit, and through the corresponding shaper of short pulses 9 and shch4

The rator 10 records the next A2 in the pulse counter 3 (in Fig. 2, A2 5). The operation process is repeated until shift register 8 returns to its original state. Beginning from this moment the program is repeated.

Formula inventions

A device for generating a serge pulse, containing a paraphase generator, the first output of which is connected to one of the inputs of the element I, the other input of which is connected to the trigger output, the first input of which through the first pulse counter is connected to the second output of the paraphase generator and with the input of the second pulse counter, characterized in that, in order to obtain a series following period, independent of the number of pulses in the series, the element NO and the program storage unit are added to it, the output of which The bit is connected to the corresponding bits of the second pulse counter, the output of which is connected to the first input of the NO element, the output of which is connected to the second m of the trigger input, the first inlet of which is connected to the discharge bits of the second pulse counter, the second input of the element NO to the input of the program storage unit.
