Abstract

PURPOSE:To generate an output signal corresponding to the contents of a broadcast signal by automatically switching a change-over circuit in accordance with the contents, by bringing a detection circuit and the change-over circuit, provided to a receiver, under digital control. CONSTITUTION:This receiver consists of detection circuit 5 detecting a sound intermediate frequency signal, LPF6 separating a main channel signal from the output signal of circuit 5, BPF7 separating a control signal from a sub-channel, amplifier- detector circuit 10 further detecting a FM wave, LPF11, positive and negative signal generating circuit 12, transistor 13, and detection circuit 14 converting a control channel signal extracted from filter 7 into a two-bit digital signal. Then, detection circuit 14 is composed of an amplifier circuit, detection circuit, single-frequency signal passing filter, and digital signal generating circuit. In addition, matrix circuits 24 and 25, and a change-over circuit of electronic switch circuit 31 are provided. Among them, the amplifier circuit, matrix circuits, change-over circuit, detection circuit, etc., are integrated to simplify the circuit constitution.
