Five-Input Majority Voting Logic

This circuit determines whether the majority of the input signals are logic 1s or logic 0s. If the majority of the input signals consist of 1s the output is set to logic 1 otherwise it will be at logic 0. This particular version has five inputs, and the circuit is a direct (i.e, no attempt was made to simplify the circuit) implementation of the function. The circuit simply checks if any three combination of the input signals are all 1s. This is done by using ten three-input AND gates with the outputs ORed together.
