Abstract

PURPOSE: To demodulate the modulating wave having different center frequency, by counting the pulse at the conversion point for the polarity of the FM modulating wave given with rectangular wave with the binary counter and by adding or subtracting a constant determined by the FM modulating frequency to this output.
