Abstract
PURPOSE: To make possible signal transmission of high fidelity by synthesizing correction signal from the discrimination output signal obtained through level discrimination and compensating the waveform distortion produced in clip processing.
CONSTITUTION: An AND circuit 12 outputs the signal of triangle waveform as the analog AND output signal of the comparison output signal delayed by a specified delay time T2 in a delay circuit 10 and the output signal from a charging-discharging circuit 9. The AND output signal obtainable from the AND circuit 12 is supplied to a signal mixing circuit 7 and is superposed with the demodulation signal having been delayed by a specified delay time T1 in a first delay circuit 6. Namely, a signal mixing circuit 7 is supplied with the demodulation signal with a delay by the specified delay time T1 and the AND output signal of triangle waveform is superposed in the portion shown by a broken line in the figure where the waveform distortion is produced in this demodulation signal, whereby the improvement of signal distortions is accomplished.
