The diagram displays a waveform analysis for a J-K flip flop circuit. The topmost waveform represents the clock signal, shown as a series of square pulses that alternate between high and low states. Below the clock signal, three waveforms represent the input signals and the output state:

1. **J (Set input):** This waveform comprises high and low states. It represents the 'Set' input for the J-K flip flop, altering between high (1) and low (0) states at defined intervals.

2. **K (Reset input):** Similar to the J input, the K waveform fluctuates between high and low states, signifying the 'Reset' input for the flip flop.

3. **Q (Output):** This is the output waveform, which needs to be drawn based on the J-K inputs and the initial state assumption that Q starts at 0. As per the J-K flip flop behavior:
   - If J=K=0, Q remains unchanged.
   - If J=0 and K=1, Q resets to 0.
   - If J=1 and K=0, Q sets to 1.
   - If J=K=1, Q toggles its state.

The diagram concludes with an incomplete section for the Q waveform, indicating the need for analysis and plotting based on the initial condition and input waveforms.

This exercise requires understanding the behavior of J-K flip flops to determine how the output (Q) should be drawn in response to the given clock, J, and K waveforms.

**7) Problem Statement:**

Draw the curve of the bit Q given the J-K flip flop inputs below. **This time,** assume the bit Q starts with a value of 1.

**Inputs Diagram:**

- **Clock (Top Line):** This is the clock signal, consisting of a series of square wave pulses.

- **J Input (Second Line):** The J input is a digital signal that changes between high and low states.

- **K Input (Third Line):** The K input is another digital signal that varies between high and low states.

- **Q Output (Fourth Line):** This is the line where the curve of the output Q should be drawn by the student. Q starts with an initial value of 1.

**Instructions:**

Using the given J and K inputs, draw the resulting Q output that conforms to the operation of a J-K flip flop. Note that the initial value of Q is 1. The behavior of the J-K flip flop should be used to determine the transitions in the Q output based on the inputs provided.
