ABSTRACT:
A tuner for use in two systems utilizes a determining circuit to determine whether or not a baseband signal, after demodulation includes a sound carrier. If a sound carrier is present, the determining circuit determines that the received television signal is a television signal in the NTSC system, if the carrier signal is not present, a television signal in the MUSE system. When the received television signal is a television signal in the NTSC system, switches are activated such that the baseband signal is applied to a signal processing circuit for video and a signal processing circuit compatible with the NTSC system. An averaging AFC is selected by these switches. On the other hand, when the received television is a television signal in the MUSE system, switches are activated such that the baseband signal is applied to a MUSE decoder and a keyed AFC is selected.
