Abstract: PURPOSE: To obtain an excellent regenerated picture by using a signal, obtained by differentiating a unipolar signal twice when converting the unipolar signal with a half tone of a facimile or the like into a multipolar signal.  
     CONSTITUTION: In the signal change point detection circuit of the transmission-side modulation part, unipolar signal A is differentiated by differentiating circuit 7 to obtain signal B, which is differentiated again by differentiating circuit 8 to obtain signal C. When signal C exceeds a fixed level, AND circuit 11 outputs the zero- cross point of signal B and when signal A exceeds the fixed level [signals a and b], slice circuit 12 generates its output; in either case, a signal point signal is outputted from OR circuit 13. In this case, the amplitude of signal C varies with the pulse [(a), (b), (c), or (d)] widths of signal A, waveform intervals of signals B and C widen with sufficient pulse widths [(a) and (d)], and the amplitude of signal C increases with narrow pulse width (c). Therefore, the remarkable fringe of the leading edge of a half-tone part and the disappearance of a thin line can be prevented.
