An analog angle modulated signal is converted into a digital signal within an A/D converter using a sampling clock having a frequency an integer times higher than the carrier of the angle modulated signal. The digital signal is delayed by one sampling slot within each of the delay circuits connected in series to the A/D converter. The output of the A/D converter and that of the fourth delay circuit from the A/D converter are multiplied by -1/2 within the respective digital weighting circuits, respectively, and the multiplied outputs as well as the output of the second delay circuit from the A/D converter are added together to generate an I component level signal. The output of the first delay circuit is multiplied by -1 within another weighting circuit and this multiplied output as well as the output of the third delay circuit are added together to generate a Q component level signal.
