2’s complement representation of a 16-bit number (one

Home » Microprocessor » Advanced Microprocessors » Question

2’s complement representation of a 16-bit number (one sign bit and 15 magnitude bits) is FFFI. Its magnitude in decimal representation is—

1. 0
2. 1
3. 32,767
4. 65,767

Correct Option: C

FFF 1 = 16³ × 15 + 16² × 15 + 16¹ × 15 + 16⁰ × 15
= 32,767
