Explanation:
A J-K flip-flop is a type of flip-flop used in digital electronics. It has two inputs, J and K, and two outputs, Q and Q'. When the clock input is triggered, the output of the flip-flop changes based on the values of J and K.
In this question, J = 1 and K = 1, which means that the output of the flip-flop will toggle every time the clock input is triggered. This will result in a square wave output at the Q output.
Since the clock input is 20 kHz, the frequency of the square wave output will also be 20 kHz. However, since the flip-flop toggles on both the rising and falling edges of the clock input, the duty cycle of the output waveform will be 50%, resulting in a 10 kHz square wave.
Therefore, option D is the correct answer.
Key Takeaways:
- A J-K flip-flop is a type of flip-flop used in digital electronics.
- J = 1 and K = 1 will result in a square wave output at the Q output.
- The frequency of the square wave output will be the same as the clock input frequency.
- The duty cycle of the output waveform will be 50%, resulting in a 10 kHz square wave.

As one flip flop is used so there are two states available. So, 20/2 = 10Hz frequency is available at the output.
