ABSTRACT:
A bivalent signal generating circuit in which an input signal having a substantial sinusoidal waveform can be converted to a bivalent signal without causing chattering: in this bivalent signal generating circuit, the bivalent signal is generated by comparing the input signal with a hysteresis width, and the circuit is arranged such that the hysteresis width is varied in accordance with a signal level of the input signal. Therefore, even if a noise is superimposed upon the input signal and thus the level of the input signal becomes large, it is possible to generate the bivalent signal in a correct and stable manner.
