ABSTRACT:
A frequency processing circuit has a suppressing circuit for suppressing a lower sideband wave of an input FM signal whose frequency is modulated, a frequency conversion circuit for converting the frequency of an output of the suppressing circuit, and an emphasizing circuit for emphasizing a lower sideband wave of an output of the frequency conversion circuit. The emphasizing circuit emphasizes a share of the amount of the wave suppressed by the suppressing circuit.
