<p>A television sound receiver is disclosed which includes an input terminal for receiving a television sound signal, a tuner connected to the input terminal, a channel selector connected to the tuner, an intercarrier sound demodulating circuit connected to the tuner, a splitcarrier sound demodulating circuit connected to the tuner, a sound signal output terminal, and a switching device for selectively and operatively connecting one of the intercarrier and split-carrier sound demodulating circuits between the tuner and the sound signal output terminal and the switching device. In this case, the switching device includes a timing generator connected to the channel selector for generating a pulse signal of a predetermined period responsive to a channel selection period of the channel selector, a first operational circuit for normally connecting the split-carrier sound demodulating circuit operatively between the tuner and the sound signal output terminal, and second operational circuit connected to the timing generator for connecting the intercarrier sound demodulating circuit operatively between the tuner and the sound signal output terminal during the predetermined period.</p> |
