ABSTRACT:
A noise removing circuit is disclosed for removing noise of a duration shorter than a predetermined period of time from an input signal. A monitor circuit is provided for monitoring the input signal to detect whether each time interval occuring between a change detected and a just succeeding change in the input signal is longer or shorter than the predetermined period of time. An output signal is delivered from a one-bit memory. A selector is provided for selectively applying the input signal or the output signal to the one-bit memory in dependent upon whether the time interval between the changes in the input signal is longer or shorter than the predetermined period of time, so that noise of the duration shorter than the predetermined period of time is not included in the output signal.
