ABSTRACT:
A data receiver for transmitting data by changing the data into transmitted frames and by phase-modulating the data in a digital manner has a demodulation circuit for demodulating a phase-modulated signal by sync detection, a conversion circuit for converting the phase of an output from the demodulation circuit into a correct phase, and a sync detection circuit for detecting sync data of the transmitted frames from an output from the conversion circuit and for controlling the conversion circuit on the basis of a sync data undetected condition.
