Question

Design a combinational circuit with four inputs: A, B, C, and D, and one output, F. F is to be equal to 1 when A= 1, provided that B = 0, or when B = 1, provided that either C or D is equal to 0. Otherwise, the output is to be equal to 0.

a) Obtain the truth table of the circuit.
b) Simplify the output function.
c) Draw the logic diagram of the circuit, using NAND gates with a minimum
number of gates.
