Majority voter: Signal probability, reliability and error bound characteristics

The importance of reliability in majority voter is due to its application in both conventional fault-tolerant design and novel nanoelectronic systems. A better understanding of signal probability, functional/signal reliability and error bound of majority voter is discussed in this paper. We analyze these parameters by boolean difference. The equations derived in this paper present the characteristics of error propagations in majority voter, and reveal the conditions that TMR (Triple Module Redundancy) technique requires. The results show the critical importance of error characteristics of majority voter, as used in fault-tolerant designs.
