Question

Complete the following timing diagrams for Q and Q¯ for each FF type. Assume they are triggered on the positive rising edge of the clock (C).

**JK Flip-Flop (JKFF) Timing Diagram Explanation** The image shows a timing diagram for a JK flip-flop (JKFF), a type of digital memory circuit used in various electronic applications. The diagram consists of five waveforms labeled J, K, C, Q, and the complemented Q (often denoted as Q̅). Each waveform illustrates the behavior of the JK flip-flop over time. 1. **J Input (J):** This waveform represents the "J" input of the JK flip-flop. It has several high (logic 1) and low (logic 0) transitions. The state of the J input influences how the flip-flop changes states. 2. **K Input (K):** This waveform represents the "K" input of the JK flip-flop. Similar to the J input, it has high and low states. The K input, together with the J input, determines the behavior of the flip-flop. 3. **Clock (C):** This is the clock input waveform. It consists of a series of regular pulses and is crucial for synchronizing the changes in the output states of the flip-flop. On each positive or negative edge of the clock pulse, the flip-flop evaluates the J and K inputs to determine the next state. 4. **Q Output (Q):** This waveform shows the Q output of the flip-flop. Depending on the J and K inputs and the clock's trigger, Q changes its state. Q represents the flip-flop's main output. 5. **Complemented Q Output (Q̅):** This is the complemented or inverted Q output waveform, also known as Q-bar. It is simply the inverse of the Q output. **Behavior Summary:** - When J = 1 and K = 0, the Q output is set (Q = 1). - When J = 0 and K = 1, the Q output is reset (Q = 0). - When J = 1 and K = 1, the Q output is toggled (changes state). - When J = 0 and K = 0, the Q output remains unchanged. **Usage:** JK flip-flops are essential components in digital circuits, often used for counters, shift registers, and various memory applications to maintain a stable state defined by control signals.
