Abstract

PURPOSE:To reduce the time constant and to short the time until a proper gain is obtained at the channel selection time, and to increase the time constant and to avoid the distortion increase at the low-range modulation wave after the channel selection, by securing an automatic switching between the non-tuning and the tuning times for the time constant of the LPF which constitutes an AGC circuit.
