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