PURPOSE:To execute a demodulation even against an input signal as well to which the carrier of a phase intersecting orthogonally with a binary shift keying signal is superposed, by switching the phase of a regenerated clock by a carrier detecting device. CONSTITUTION:The binary shift keying signal is inputted from an input terminal 1, the carrier detection of an input signal is executed by a carrier detecting device 5, and in accordance with whether a carrier exists or not, the phase of a clock regenerated by a clock regenerating device 3 is switched by a phase switching device 6. In a demodulating circuit 2, the multiplied product detection of the regenerated clock outputted from the phase switching device 6 and the input signal is executed, and a demodulating signal is outputted to an output terminal 4. |
