SR NOR Latch: Memory Phase Duration Verification

MediumLogic CircuitTiming Diagram

An active-high SR NOR latch serves as a fundamental memory element that retains its stored state indefinitely until explicitly overwritten. The latch forces its output Q to 1 when S is 1 and R is 0, and holds its current state when both inputs are 0. Three signals are shown: S (set input), R (reset input), and Q (output, initially 0). Trace Q across all 16 time steps.

Constraints

  • The output Q responds asynchronously and immediately to changes in S and R.
  • The memory state must persist without degradation as long as both inputs remain at 0.

Solve this problem

Place the gates, wire them up and watch the signals settle. Every submission runs on the same simulation engine that grades it.
