Explanation:
Detailed explanation-1: -Explanation: There are 2 AND, 1 OR and 2 EXOR gates required for the configuration of full adder, provided using half adder.
Detailed explanation-2: -1. Half Adder : Half Adder is a combinational logic circuit which is designed by connecting one EX-OR gate and one AND gate. The half adder circuit has two inputs: A and B, which add two input digits and generates a carry and a sum.
Detailed explanation-3: -Total five 2x1 MUXES required. Half adder with 1 XOR gate and 1 AND gate requires two muxes (1 for XOR gate & AND gate each). Two half adder alongwith one OR gate makes a full adder.
