ABSTRACT:
A digital receiver has a receiving section for receiving a digital modulated signal, a digital demodulation section for judging a logical state of a detection output signal obtained by performing a digital detection operation for the digital modulated signal, for demodulating the digital modulated signal and for generating a data signal. The digital demodulation section has a binary conversion circuit for converting the data signal into a binary signal and a receiving quality detection device for detecting a receiving quality of the data signal based on a wave-form of the binary signal. The receiving quality detection device has a pulse generator for generating pulses having a time width between a positive pulse width of the wave-form of the binary signal based on the digital modulated signal and a time width between a third time width and a time width which is obtained by subtracting a negative pulse width of the wave-form of the binary signal from a second pulse width. The digital demodulation section has a wave-form shifter for shifting the wave-form of the binary signal of the in phase, a data judgement device for judging a state of the detection output signal based on a synchronous clock signal, and an exclusive OR device for performing a logical exclusive OR operation between the wave-form of a wave-form of output from the data judgement device and a wave-form of output from the wave-form shift means.
