Abstract

PURPOSE:To avoid the necessity of providing a system switching means at the panel side, by detecting the reception of a digital modulation signal and switching the reception output of a digital demodulating circuit and an FM demodulation circuit. CONSTITUTION:A detection circuit 20 supplies a detection signal to a voltage comparison circuit 19. The voltage comparison circuit 19 outputs a signl switching signal by taking an output of a signal selection circuit 23 for a digital demodulation signal the absolute value of the detection signal is greater than the comparison voltage of a constant voltage generating circuit 18 as the reception of the degital modulation signal, and for an FM demodulation signal when smaller than the comparison voltage as the reception of the FM modulation signal. This demodulation signal output is amplified at an amplifying circuit 24 and applied to the output termial of a demodulation signal 25 as the output for speakers and the like.
