Abstract

PURPOSE: To allow a divider circuit to discriminate easily and definitely a signal between modulated waves of two adjacent signal frequencies.
CONSTITUTION: The 1st and 2nd signal frequencies are denoted by (f1) and (f2) respectively, and the carrier frequency is by (f0). A signal inputted to input terminal 1 is demodulated 3 to obtain signals of (f1) and (f2). The carrier signal is inputted to frequency divider 5 with divisor N which is an integer satisfying the relation of f1<f0/N<f2. In this case, the carrier is inputted not direct but by way of synchronous oscillator 8 to obtain an excellent S/N signal. The demodulated wave is discriminated from the divided carrier by frequency comparing discrimination circuit 6.
