Filed: 1986-09-18
Abstract: PURPOSE:To facilitate the large scale integration by processing the result of AD conversion of an FM modulation wave digitally so as to apply FM demodulation thereby eliminating the change in the characteristic due to the variation of components. CONSTITUTION:The FM modulation wave inputted to an input terminal 1 is AD-converted by an AD converter 2 into a digital signal. The digitized signal is fed to a differentiation computing element 2 and a 90 deg. phase shifter 4. The outputs of the computing element 3 land the phase shifter 4 is given to a divider 5, where the output of the differentiation computing element 3 is divided by the output of the 90 deg. phase shifter 4 so as to eliminate the polarity of terminals and the effect of a carrier as required. The output of the divider 3 is extracted as a digital signal corresponding to an FM-demodulated signal from an output terminal 6.
