1. Consider the function f = ? m(0, 1, 2, 6). Use the truth table to derive a circuit for f that uses a 2-to-1 multiplexer.
2. Consider the function f = ? m(0, 1, 2, 6). Use the truth table to derive a circuit for f that uses a 4-to-1 multiplexer.
3. Consider the function f = ? m(0, 1, 2, 6). Use the truth table to derive a circuit for f that uses a 8-to-1 multiplexer.
4. Consider the multiplexer-based circuit illustrated in Figure P4.1. Show how the function f = w2w3' + w1w3 + w2'w3 can be implemented using only one instance of this circuit.
