ABSTRACT:
A signal processing circuit for eliminating noise from an input binary signal includes a measurement part and a signal output part. The measurement part measures the cumulative period of time of at least one of high-level and low-level states of the input binary signal for a predetermined period of time after the polarity of the input binary signal is inverted. The signal output part outputs at least one of high-level and low-level signals in accordance with the cumulative period of time.
