Abstract
A circuit for debouncing a signal from a switch or other input. The invention provides an arrangement which receives an input signal and which monitors the input to provide an output which switches after a predetermined time from the input signal changing from one state to another. However, the output changes back to its original state in a much shorter time if said input changes back to its original state.
