Question

An overflow occurs in _________

(a) MSD position

(b) LSD position

(c) Middle position

(d) Signed Bit

I have been asked this question in an interview for internship.

I would like to ask this question from 1’s, 2’s, 9’s & 10’s Complements topic in portion Number System and Codes of Digital Circuits

Answer 1

Right option is (a) MSD position

For explanation I would say: An overflow occurs at the Most Significant Digit position. It occurs when the processor cannot handle the result properly when it produces an out of the range output.
