Abstract

PURPOSE:To avoid mischannel selection even with faster channel selection operating speed, by sufficiently making small the time constant of gain control time constant circuit of signal system than that at listening of signal wave, only during channel selective operation. CONSTITUTION:A drive circuit 13 is operated during the channel selective operation in automatic or manual selection of broadcast signal wave. Thus, the time constant of a gain control time constant circuit 12 is made small and the leading time of AGC control is made small. Thus, even with faster channel selective operation, the mischannel selection due to the saturation of the circuit can be prevented. Further, after the end of channel operation, the circuit 12 can be made to normal receiving state, and the reproduction of normal signal can be made possible.
