Abstract
PURPOSE:To enable to reject the cross talk component with a simple constitution, by forming the waveform opposite in the polarity from the signal demodulating FM waves and adding the cross talk signal waveform expected at the envelope detector output terminal. CONSTITUTION:The signal (b) demodulated 4 for the frequency modulation wave (a) from the input terminal 1 is outputted at the output terminal 7 and fed to the full wave rectifying circuit 10, and the output signal (d) is fed to the level adjuster 13 via the nonlinear circuit 11 (having nonlinearity suitable to produce the waveform similar to the cross talk signal waveform obtained at the output terminal of the envelope detector 6). On the other hand, the signal demodulated (c) obtained from the detector 6 is fed to the adder 12 with the signal (e) and the output signal (amplitude modulation component demodulated from the amplitude modulation waves) is fed to the output terminal 9, but since the waveforms (c) and (e) are opposite for the polarity each other, no cross talk component can be present at the terminal 9.
