Description

the first input of the second flip-flop 4 through the switch 9 is given a signal from the output of the splitter 7. This signal flips the flip-flop 4 from the zero to one state. The signal from the output of the trigger 4 is fed to the control input of the key 8, preparing it to pass the counting pulses from the generator 5 to the counter 11.

At the moment of the first comparison of the input signal with the sawtooth voltage, a pulse appears at the output of the comparison unit 1, which passes through the switch 10 to the reset bus of the divider 7. At the same time, the pulse from the output of the comparator is fed to the first input of the trigger 3, causing it to be reset to zero state the The control input of the key 9, the signal from the trigger 3 is not received. The pulse from the output of the comparison unit is fed to the second input of the trigger 4, transferring it to the zero state. The key 8 is closed, and the pulses from the generator 5 pas counter 11 are not passed. Thus, the number of pulses in the counter is proportional to the initial amplitude of the input signal.

At the time of the second start of the generator 2 sawtooth voltage, the signal from the output of the divider 6 is fed to the second input of the trigger 3, causing it to trigger. The control input of the key 9 comes from the output of the trigger 3 signal "1. After a time interval equal to the sawtooth generator generator (device measurement scale), after the first operation of the comparison unit, the first input of the second trigger 4 through the key 9 receives a signal from the output of the divider 7. This signal triggers the trigger 4, and at its output The signal "1 opening key 8 for passing pulses from the generator 5 pulses to the counter 11.

If during the sweep period the input signal has increased, then pulses are passed through the switch 8 to the counter up to the moment of the second comparison of the input signal with the sawtooth voltage. At the moment of the second comparison of the input signal with the sawtooth voltage, a pulse from the output of the comparison unit 1 is fed to the reset bus of the divider 7 through the public key 10, as well as to the second input of the trigger 4, returning it to the zero state.

Thus, on the counter 11, the pulses are summed, the number of which is proportional to the increment of the input signal in the area between adjacent operations of the comparison unit.

When the input signal decreases, comparison unit 1 is triggered before divider 7 doesn’t re-trigger trigger 3 to the zero state and close key 9, preventing the signal from divider 7 from passing to the nerve input of trigger 4 until the input level

the signal will not reach the level of the previously memorized maximum. When the measured signal exceeds the previously stored maximum, divider 7 is triggered earlier than block 1 of the comparison. At the first input of the trigger 4

A signal is sent through the public key 9, which triggers the trigger 4, which, in turn, prepares the key 8 for passing 11 pulses to the counter, the number of which is proportional to the new increment of the current signal.
