We consider a circuit having four inputs and one output. The output has the value 1 if at least half of the inputs have the value 1. In this case, the circuit is a not-a-minority circuit.
1) Build a truth table for the circuit presented in the description above.
2) Using this truth table, find a Boolean expression which represents the same function, and by using Boolean algebra, simplify it as much as possible.
3) Verify the design of the circuit.
6. For the following Verilog code, draw the corresponding circuit diagram for "bigMod". Your circuit
should only involve standard gates (AND, OR, NAND, NOR, XOR, Inverter), and the variable names Val,
X, Y, and Z. DO NOT SIMPLIFY THE CIRCUIT. Note: all of the code is legal Verilog, with no errors.
