Abstract

PURPOSE:To prevent the occurrence of an undesired demodulation output, by incorporating a switch circuit within a PAL or SECAM color signal demodulating circuit. CONSTITUTION:A switch circuit (which performs a conduction between terminals 23 and 24 in case of a PAL color signal and a nonconduction between terminals 23 and 24 in case of a SECAM color signal) is provided within a PAL color signal demodulating circuit 16. At the same time, a switch circuit (which performs a conduction between terminals 25 and 26 in case of a SECAM color signal and a nonconduction between terminals 25 and 26 in case of a PAL color signal) is provided in a SECAM color signal demodulating circuit 17. As a result, no signal emerges at a SECAM color signal demodulation output terminal 6 in case of a PAL color signal, and no signal emerges at a PAL color signal demodulation output terminal 5 in case of a SECAM color signal. Thus a stable operation is secured for a PAL/ SECAM switch circuit 22.
