Abstract
A system for filtering multiple event signals from multiple event-generating sources. A selection circuit receives the multiple event signals and selects one of the event signals. A filter circuit is coupled to the selection circuit and receives the selected event signal from the selection circuit. The filter circuit produces a filtered event signal. A counter receives the filtered event signal from the filter circuit and is incremented in response to the filtered event signal. The filter circuit includes a comparison logic circuit and an edge detection logic circuit.
