Thanks, helped me figure out how overflow connected in with everything!

01 + 01 = 10 which seems 2 but it is not if we are dealing with signed numbers and actually 10 is -2 (not 2). Now the idea of using the last two carry bits seems flawed. plz, Mr. Padraic correct me if I am wrong. I am very open to discuss this to remove any confusion I might have. Thanks

Can someone please tell me how will this problem be solved? I mean how can we resolve this problem if overflow has occurred in our circuit??
