Multiple choice

In a sequential circuit, the output depends on

  1. present state only

  2. past inputs only

  3. both (1) and (2)

  4. none of these

C Correct answer
Explanation

In sequential circuits (like flip-flops, counters), the output depends on both the present inputs and the present state (which stores past inputs). This memory of past states is what makes it 'sequential'. Combinational circuits depend only on present inputs.
