PROBLEM TO BE SOLVED: To provide a duty correction circuit with a low bit error rate by means of demodulation using signals whose waveform distortion is corrected. SOLUTION: Waveform distortion is detected by observing waveforms and the distortion is corrected. Even when it is impossible to maintain a duty ratio of 50% of a received Manchester signal, the ratio of a corrected signal becomes nearly 50% by using this duty correction circuit, and a more accurate regeneration clock can be generated. Also by using a highly accurate generation clock and signals whose distortion is corrected, demodulation with a low bit error rate can be realized.
