Give a circuit that computes each function on input variables x, y, and z. If you construct an input/output table for the function, you may end up with a Boolean expression that results in a complex circuit. You may want to use the laws of Boolean algebra to simplify the Boolean expression before drawing the circuit. Alternatively, you can reason about the function in order to derive a simple Boolean expression that expresses the function. (a) If x = 0, the circuit will output y + Z. If x = 1, the circuit will output yz. (b) The output is 1 if at least two of the three inputs are 1 . c) The output is 1 if the value of x is equal to the product of y and z
