A circuit and method for debouncing an electrical signal are disclosed. A representative embodiment of the present invention may be set to remove (i.e., filter) noise or glitches in the low and high portions of an input signal, where the width of the noise or glitches while in the high or low state may be set using a programming interface. The filtering is done in a manner that results in a clean, debounced output signal having a low portion approximately equal to the low portion of the input signal, and a high portion approximately equal to the high portion of the input signal. Noise or glitches of less than programmable high or low glitch widths are filtered from the input signal and do not appear in the output signal.
