Abstract
A time domain signal filter detects a change in an input signal and replaces the input signal with an internally generated substitute signal for a filter period. The filter period is user selectable and can be set through a bit in a hardware register. After passage of the filter period, the time domain signal filter resumes direct supply of the input signal as the output signal. The time domain signal filter determines the start of the filter period by using either the falling edge or the rising edge of the clock input, whichever edge comes first after detecting the change in the input signal.
