(a) An underflow condition

(b) A neutral condition

(c) An overflow condition

(d) One indication

This question was posed to me in an online interview.

My question is based upon Procedure for the Design of Combinational Circuits topic in section Arithmetic Circuits of Digital Circuits

Answer 1

The correct option is (c) An overflow condition

For explanation I would say: If the two numbers include a sign bit in the highest order position, the bit conditions of interest are the sign of the result, a zero indication and an overflow condition.
