Title: Automatic level controller
Inventor: KAGOHARA AKIO
IPC: H03G3/20
Filed: 1982-12-28
Abstract: PURPOSE:To speed up the following speed of control by making one-circulation DC gain of a gain controlling loop equal to twice the repeating frequency of an input signal. CONSTITUTION:In case the relation of the one-circulation DC gain K and the pulse repeating interval T of an input pulse modulating signal is K>2/T, the polarity of an output from a zero-order holding circuit 4 holding the sample of an input signal is not changed.

The use of said characteristics makes it possible to discriminate K>2/T, K=2/T or K<2/T and control a gain variable amplifier circuit 8 so as to form K=2/T. Thus, the time required for the control of automatic level controlling operation for pulse signals can be shortened.
