Abstract

PURPOSE:To obtain the optimum reception state by making the regeneration and display within the narrow-band frequency range when there is an adjacent channel and within the wide-band frequency range when no adjacent channel. CONSTITUTION:Relatively-narrow band and relatively-wide band IF circuits 11 and 12, and adjacent channel signal detection circuit 13 are cascaded to front end 10 in parallel; and then, the connections are so made that if the output of circuits 13 is generated, switching circuit 14 changes over to the circuit 11 side by being supplied with outputs of circuits and when circuit 13 has no output, circuit 14 changes over to the circuit 13 side. Namely, when an adjacent channel resides, the generation is done within the narrow-band frequency range and when no adjacent channel, it is done within the wide-band frequency range. According to the output of circuit 13, display unit 16 is driven so as to discriminate whether the reception is done in a narrow band or wide band. Consequently, the optimum reception state can be obtained.
