ABSTRACT:
An input signal processing apparatus for use in a comparator which compares an input signal with a reference voltage signal to output a signal inverted in accordance with a comparison result. The apparatus detects the frequency of an input signal from a rotation detecting device such as pickup coil so that a mask time is set in accordance with the detected input signal frequency. The apparatus separates the levels of the input signal and a reference signal to the comparator for the mask time. The mask time is set so as to vary with a first predetermined rate of change when the input signal frequency is below a predetermined frequency and vary with a second predetermined rate of change greater than the first predetermined rate of change when the input signal frequency is above the predetermined frequency. This arrangement can appropriately set the mask time whereby it is possible to prevent the phase shift in waveshaping when the frequency of the input signal is high.
