ABSTRACT:
A digital signal processor for performing phase or frequency signal processes, for example, demodulating processes of modulation signals such as PSK signals. This processor is provided with amplitude-to-phase converting means which receives two digital input signal series that are respectively expressed by a plurality of bits and that have a quadrature phase relation with each other, and which outputs the digital phase information signal corresponding to a combination of the digital values of those input signal series, this combination being amplitude information. This processor then supplies the phase information signal which is outputted from the amplitude-to-phase converting means to signal processing means, thereby digitally processing the phase information signal.
