What is the behavior of a JK flip-flop when both J and K are set to 1?

• A. It resets
• B. It sets
• C. It toggles
• D. It remains unchanged

Answer: (C)

A JK flip-flop is a type of bistable multivibrator and is a fundamental building block in digital electronics, particularly in sequential circuits. Its behavior is defined by the states of its inputs, J and K, and the clock signal. When both J and K inputs are set to 1, the JK flip-flop enters a toggle mode. This means that every time the clock signal transitions (usually from low to high), the output state of the flip-flop will change to the opposite of its current state. If the flip-flop's output (Q) was previously high (1), it will change to low (0) and vice versa. This behavior allows the JK flip-flop to effectively "toggle" its output with each clock pulse, making it a crucial component for counters and other sequential logic circuits. The toggle behavior is distinct from setting or resetting the flip-flop (which would happen if only J or K was active). Therefore, when both inputs are high, the JK flip-flop's characteristic toggling action is activated, aligning with the answer.
