The clocked SR flip-flop consists of two inputs, S and R, a clock input (CLK), and two complementary outputs, Q and Q̅. The operation of the clocked SR flip-flop depends on the level or edge of the clock signal. When the clock is inactive (depending on whether the flip-flop is positive- or negative-triggered), the outputs remain in their previous state regardless of changes in S and R inputs. When the clock is active, the
