16a 4-Bit Binary Adder/Subtractor | Overflow Detection | Digital Logic Design

4-bit binary adder circuit can be reused to perform 4-bit binary subtraction. For that purpose, we take 2's complement of the subtrahend and add with the minuend.
The addition and subtraction of signed numbers can cause an overflow. The overflow can be from the upper limit or lower limit. An overflow can be detected by checking the last and second last carry bits. If both bits are same then no overflow happened and if both carry bits are different then overflow happened.

Amazing video. Really helped me understanding this type of circuit. Excellent work!

[@dhawalpatil7779]

Thanks you

[@dhawalpatil7779]

Op sir

[@dikshabagade5542]

The way u explain is really amazing, thank you so much sir

[@Aarsh2023]

Sir con u make the same video in Hindi

[@xavier4107]

Can we use unsigned binary numbers in binary adder-subtractor ?if possible, then how can we proceed if we got no carry case in subtraction operation ?
