Abstract :
A self-purging system is proposed which uses a digital voter that automatically adjusts the threshold of the voter as failed modules are purged. The switch used is no more complex than the switch used by the self-purging redundancy proposed by Losq (1976). However, the system presented here can tolerate single module failures at any given time. This system is useful for applications in which aging or stress is the cause of failure rather than noise
