SU1594679A1 - Converter of sum of durations of n pulses into single pulse - Google Patents

Abstract

The invention can be used in systems for processing and generating pulse signals. The purpose of the invention is to expand the functionality achieved by providing a conversion of the sum of the durations of the N pulses. The converter contains a pulse counter 1 and two elements 2 and 3 of coincidence. The introduction of the third match element and shift register 6 allows the conversion of the sum of the durations of several pulses, which expands the functionality of the converter. 3 il.

The invention relates to a pulse technique and can be used in processing systems and forming pulse siglals.

The purpose of the invention is to expand the functional possibilities by ensuring the conversion of the sum of the durations of N pulses,

a logical unit appears on the N-M output of shift register 6, i.e. the leading edge of the output pulse, in connection with which the second (subtracting) input of the pulse counter 1 begins to receive reference frequency pulses. At the moment when the counter is cleared from its output, a short pulse is formed, as a result of which the shift register 6 returns to its initial state and the rear front of the output pulse is formed on the output bus 9.

If, on the coincidence element 2, one frequency is supplied, and the other coincides on the input of the element 3, then the duration of the impulse is equal to the ratio of the specified frequencies multiplied by the total duration n input5 connected to the first inputs of the element 20 b1X pulses.

With the arrival of the first input pulse on bus 5, the coincidence element 2 starts to pass on the clock 1 counter input of the counter 1 frequency reference pulses. On the back edge of the first input pulse, the logical unit is written to the first bit of the shift register 6 and simultaneously to the summing input of the counter 1 the arrival of pulses ceases, With the arrival of the second pulse during the time of the pulse duration, the counter pulses again, and on the falling edge the logical unit is rewritten into the next register bit 6
