Abstract

PURPOSE:To realize switching of each mode with the control signals in a single series, by detecting the type of the broadcast now receiving and applying selectively the control signal to the corresponding mode switching means. CONSTITUTION:The output of a control signal detecting circuit 260 of stereo broadcasting is set at a high level when a low-level detection output such as 0V is being led out of a control signal detecting circuit 250 of double-broadcasting. The control signals of one series which are supplied through a terminal 230 are applied to the bases of transistors (TR)241 and 242 respectively. However, a terminal 211 of a switching circuit 210 of double broadcasting mode is set at a low level according to the control signal since only the collector of the TR241 is at a low level.
