A debounce circuit eliminates noise, glitches, or transient signal variations resulting from mechanical bounce occurring at a change of state of analog signals and provides a dynamic debounce period alteration and time base variation without loss of the current debounce state. The debounce circuit has a physical counter that is configured for being adjusted within a virtual counter such that the noise, glitches, or transient signal variations resulting from mechanical bounce occurring at an initiation of a change of state of an analog input signal from a source device are filtered by delaying a change of output state of the debounce circuit. The debounce circuit includes a strobe generator that produces a strobe signal that is a submultiple of a master clock that is determined by the location of the physical counter within the virtual counter that is used to increment the physical counter within the virtual counter.
