A half adder is implemented with XOR and AND gates . A full adder is implemented with 2 half adders and one OR gate.The propogation delay of an XOR gate is twice than that of AND/OR gate. The propogation delay of an AND/OR gate is1.2micro sec.A 4 bit ripple carry binary adder isimplemented by using full adders. The total propogation delay of this 4 bit binary adder is ___________
