Problem 4 (12 pts) Using NAND gate to design a combinational logical circuit. There are 3 binary inputs (A,B,c) and one output (F). When there are odd 1s in the inputs, the output is 1, otherwise 0. (You need to show your steps) 1) Complete the truth table of the circuit 2) Express F in terms of A B, and C 3) Draw this logical circuit using NAND gates
