Claims

the limits. To ensure the operation of the extra-small regulator when the input signal level changes, the output of the band-pass filter is connected to an adjustable amplifier 2, the gain of which is changed by the control voltage supplied by the second integrator 9, the second integrator is an element of the circuit automatic gain control &, which, in addition to the integrator, includes a pulse generator 12 and a threshold device 13, the input of which receives the envelope voltage from the DC amplifier. Since the simultaneous steady operation of the extreme controller, consisting of the extremum memory block 5, the comparator 6, the reverse trigger 7 of the first integrator 8, the coincidence element 1O and the first generator of pulses 11 and the automatic gain control circuit, is not necessary to ensure tracking For an extremum, when the input signal level changes, the developed circuit of the regulator provides for the phased operation of these circuits. If the input signal level goes beyond the sensitivity limits of threshold device 13, then the second integrator 9 is turned on, changing the gain of adjustable amplifier 2 until the condition is satisfied: Ui - or - ygde UQII - voltage envelope coming from the output constant-current amplifier 4,. - and - sensitivity of the threshold device. The operation of the extreme controller when the integrator 9 is switched on is terminated. To stop the extremal regulator, the two outputs of the threshold device through the PILI element and the Schmitt trigger are connected to the coincidence element 1O, at whose input the blocking voltage flows, and the pulses from the first generator 11 to the integrator 8 input stop. The extreme regulator is re-enabled after the automatic gain control circuit is terminated. Thus, in the operation of the automatic gain control circuit, the extreme point of the envelope does not coincide with the level filled by block 5, -th to ensure stable tracking of the extremum, the memory element of block 5 is reset to zero when the switch 16 is closed. The key 16 is turned on (Voltage coming from Schmitt trigger 15.
