Problem #1: A majority voter circuit
One circuit that is often found inside computing system is a majority voter. A majority voter is a circuit made of AND, OR and NOT gates that has 3 inputs and one output. The output is always the representation of the majority of the inputs. For example, if two or more of the inputs are 0, then the output is 0. If two or more of the inputs are 1, then the output is 1.
The truth table for such a circuit is shown below. the symbols a, b, and c represent input signals, while y is the output.
| a | b | c | y |
|---|---|---|---|
| 0 | 0 | 0 | 0 |
