Multiple choice

The output of a sequential circuit depends on

  1. present inputs only

  2. past inputs only

  3. both present & past inputs

  4. present outputs only
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A sequential circuit's output depends on both the present inputs AND the past inputs (stored in memory elements like flip-flops). Unlike combinational circuits, sequential circuits have memory and maintain state information, so their output is determined by current inputs plus the stored history of previous inputs.
