Although recursive voting leads to a double exponential decrease in a circuit's failure probability, a single error in the last majority gate can cause an incorrect result, hampering the technique's effectiveness. Combining recursive majority voting and multiplexing helps alleviate this problem. However, the cost of this fault-tolerant approach might not be worthwhile, depending on the nature of the faults.
