Abstract
A duplex board system comprises two functionally identical processing boards, one of the boards being in an active state and the other being in a stand-by state, each of the boards generating a state signal depicting the state thereof, wherein the stand-by state board succeeds the active state board when the state of the active state board becomes deactivated; and two cancelling units, each coupled between the two boards for receiving the state signal from one of the boards, suppressing a glitch period from the state signal generated at said one of the boards, the glitch period representing an unstable signal level transition of the state signal, and outputting the glitch suppressed state signal to the other board.
