A 4-bit unsigned saturating adder is designed to clamp any result above its maximum representable value. What output should it produce when 1110₂ and 0101₂ are added?

  • A0011
  • B1111
  • C10011

Correct Answer: B. 1111
Explanation: 14+5=19, which exceeds the 4-bit unsigned maximum of 15. A saturating adder clamps the result to 1111 rather than wrapping around.
