Question
**Exercise 4: Understanding JK Flip-Flop Waveforms** **Objective:** Draw the waveforms for the output and its complement of a negative-edge triggered JK flip-flop. **Diagram Explanation:** - **CLK (Clock):** - The clock signal waveform is a square wave that alternates between high and low states. It is used to trigger events in the flip-flop on its negative edge (falling edge). - **J (Input):** - The J input waveform is high during the first and third clock cycles and low during the second and fourth clock cycles. - **K (Input):** - The K input waveform is high during the second clock cycle and low during the other cycles. - **Q (Output):** - The Q output represents the state of the flip-flop and is affected by both the J and K inputs at the negative edge of the clock signal. - **Q' (Complement of Output):** - The Q' waveform is the inverse of the Q output at any given time. **Instructions:** 1. Observe the clock (CLK) waveform to identify the negative edges (transitions from high to low). 2. At each negative edge of the clock: - If J = 1 and K = 0, set Q to 1. - If J = 0 and K = 1, set Q to 0. - If J = 1 and K = 1, toggle the current state of Q. - If J = 0 and K = 0, maintain the current state of Q. 3. Draw the corresponding Q output waveform based on the rules above. 4. Invert the Q waveform to obtain the Q' waveform. **Conclusion:** This exercise helps in understanding the behavior of a JK flip-flop which is an essential component in digital circuits, widely used for storage and transfer of data.
