What is the countering sequence of the following circuit? Is it an asynchronous counter or a synchronous counter? Why?

### JK Flip-Flop Circuit Diagram

**Diagram Explanation:**

The diagram illustrates a JK flip-flop circuit with two flip-flops connected in series. Each flip-flop has three main inputs: J (Set), K (Reset), and a clock input. The outputs are labeled as Q₀ and Q₁.

1. **First Flip-Flop:**
   - **Inputs:** J, K, Clock
   - **Outputs:** Q (output)

2. **Second Flip-Flop:**
   - **Inputs:** J, K, Clock
   - **Outputs:** Q₁ (output)

Each flip-flop is activated by a clock signal, controlling when the flip-flops change state.

**Clock Signal:**

- Depicted as a square wave to the right.
- The clock signal is a repetitive, oscillating signal used to synchronize changes in the circuit. The rising and falling edges of the clock determine when the flip-flops should evaluate their inputs and potentially change their output states.

**Output Table:**

The table shows the state changes for outputs Q₀ and Q₁ based on the clock signal:

- The table has two rows corresponding to Q₀ and Q₁.
- The values "0" in the table denote the output state at different times synchronized with the clock pulses.

This setup highlights the sequential nature of the JK flip-flop circuit, used in digital electronics for counters, shift registers, and memory storage.
