The pulse shaper operates as follows.

In the initial state, the triggers 5, 6, 7, 16 are in the zero position, a clock pulse is sent to the input bus 9, unit 1 outputs a short pulse corresponding to the leading edge of the clock, and the shaping unit 2 to the trailing edge of the clock, through the AND groups 3 pulses do not pass because they are closed. Element And 13 prepared to open the signal with triggers 6 and 7.

The impulse corresponding to the leading edge of the clock, from the output of block 1, passes through the element I 13 to the first input of the trigger 16 and, with its back front, sets it to a single state. At the same time, at the output of block 20, a pulse appears that corresponds to the leading edge of the signal from a single output of the trigger 16, which passes to the first input of the trigger 5 and, with its trailing edge, sets it to the single state. Since the triggers 5 and 16 are simultaneously in a single state and at their zero outputs low levels of the signal that pass to the first and second inputs of the element And 18, the output of which produces a high level signal, which passes to block 19, the output which appears the pulse corresponding to the leading edge of the signal from the output element And 18.

The formation of pulses at a single output of the trigger 5 will be repeated until a signal is received on one of the buses 10 or 11, or both at once. In this case, one of the signals, or both, that are taken

The impulse from the block 19 with the falling edge 25 went to its input while it is in position, it sets trigger 16 to the zero trigger 6 and 7 in the zero state. At the same time, a high signal level passes from the zero output of the trigger 16 to the block 17 and a pulse corresponding to the leading edge of the signal is formed at the output of the block 17, which passes through the OR 22 element to the second input of the trigger 5 and sets the trigger 5 to the zero front.

Thus, at a single output 35, the formula for de trigger 5, connected to the output by bus 12, will form a pulse equal in duration to the delay time for the signal from its zero output to pass through the elements 18, 19, 16, 17, 21 circuit until the trigger 5 is set to zero. At the same time, the pulse from the output of block 17 pro,. . walks through the element 15, which was the additional element iidva.confidently prepared for opening the signals from the single element OR, while the actual output of the trigger 5, and through the signals prepared from the zero outputs of the triggers 6 and 7, element 13 passes through at the first input 50 of the trigger 16 and with its back front sets it to the unit state 40

with ifx zero outputs.

Thus, a burst of pulses at a single output of the trigger 5 connected to the output bus 12 when a single clock arrives at the input bus 9 of one clock pulse will be syymyrmed, which expands the functional capabilities of the device.

the invention

Pulse shaper auth. St. No. 976495, characterized in that, in order to expand functional possibilities by ensuring the formation of a burst of pulses, three additional pulse shaping units, an additional trigger, three additional first, second and third inputs of the first additional element I are connected to the inverse output of the third trigger, through the first additional element OR - with the output of the pulse shaping unit

em it in a single state. Thus, the pause by the mark impulses is equal to the delay time for the signal from the output of the shaping unit 17 through the structural electrical circuit elements 15, 14, 13, 16, 20, 21 until the trigger 5 is set to one.

And then, at the output of the element 18, the output signal that passes through the elements of the circuit 19, 16, 17, 22 to the second input of the trigger 5 and again sets it to the unit state. A second pulse is formed at the unit output of the trigger 5 connected with the output bus 12.

The formation of pulses at a single output of the trigger 5 will be repeated until a signal is received on one of the buses 10 or 11, or both at once. In this case, one of the signals or both at once, which passed to its input while the triggers 6 and 7 are in the zero state, is removed from the And 13 element.

went to his input when the triggers 6 and 7 are in the zero state

with ifx zero outputs.

Thus, a burst of pulses at a single output of the trigger 5 connected to the output bus 12 when one clock pulse arrives at the input bus 9 will be reset, which expands the functionality of the device.
