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 an 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, change-over circuit and selective control circuit 40 are provided. This control circuit 40 is provided with a selector circuit, control circuit, main sound signal selection button, sub-sound signal selection button, and multiple selection button.
