    • 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.
    • 一种在比较器中使用的输入信号处理装置,其将输入信号与参考电压信号进行比较,以输出根据比较结果反相的信号。 该装置检测来自诸如拾取线圈的旋转检测装置的输入信号的频率,使得根据检测到的输入信号频率设置掩码时间。 该装置将输入信号和参考信号的电平分离到比较器的屏蔽时间。 掩蔽时间被设定为当输入信号频率低于预定频率时以第一预定变化率变化,并且当输入信号频率高于第一预定变化幅度大于第一预定变化率的第二预定变化率时,屏蔽时间被设置 预定频率。 这种布置可以适当地设置掩模时间,由此当输入信号的频率高时,可以防止波形成形中的相移。
