Abstract

PURPOSE:The simplify the operation and to reduce the cost, by comparing the content of audio modulation between a television and a radio at simultaneous reception of the television and radio and locking an FM tuner when they coincide. CONSTITUTION:When a desired channel is received with a tuner 1 of a television, an audio signal A of a television is inputted to one of a comparator 5. On the other hand, an audio signal B of a tuner 6 of an FM radio is converted into a monaural signal and inputted to another of the comparator. The comparator 5 compares the signals A and B, and if the difference is above a fixed value, sweeping of the FM tuner 6 is repeated and then it is below the fixed value, the tuning voltage of the FM tuner 6 is locked with the output of a controller 10. Thus, when a picture is received on a television, the audio corresponding can be received at the FM radio receiver.
