### Circuit Analysis and Q Output Diagram

For the circuit and inputs shown, draw the Q output. Assume Q is initially low. Clear is asynchronous. Be sure your diagram clearly indicates transitions of Q relative to all inputs.

#### Circuit Diagram Explanation:

- The circuit consists of two flip-flops. 
- The first flip-flop is a D-type with inputs: Data (D), Clock, and Clear (Clr).
- The Q output of the first flip-flop feeds into the second flip-flop, which is a T-type, and the final output from the T flip-flop is shown as Q2.

#### Timing Diagram:

Below the circuit diagram, a timing diagram is displayed with the following waveforms:

1. **Clock**: A periodic signal with a regular oscillating pattern.
2. **D**: The data input with transitions correlating to specific clock cycles.
3. **Clr**: The clear signal toggles asynchronously, indicating when the flip-flop is reset.
4. **Q1**: The output from the D-type flip-flop responding to changes in inputs.
5. **Q2**: The output from the T-type flip-flop, indicating the final output state.

The timing diagram reflects the relationship between these inputs and outputs, demonstrating how the outputs Q1 and Q2 transition in response to changes in the inputs. The diagram is designed to help visualize how the flip-flops operate within the circuit based on the input signals and their timing.

**Note:** Students should focus on understanding how asynchronous clear affects the behavior of the flip-flops and how Q1 and Q2 respond to the clock pulses and toggle signals.
