Question
The image shows a timing diagram with eight digital data inputs labeled \( D_0 \) to \( D_7 \). Each line represents a binary signal that can be either high or low over time, divided by vertical dashed lines indicating time intervals.

- **\( D_0 \)** remains high during the first three intervals, drops low for two intervals, and then returns high for the last two.
- **\( D_1 \)** is high during the first two intervals, low for the third, high for the next two, and low for the last two.
- **\( D_2 \)** stays low for the first interval, high for the next four, then low for the final two.
- **\( D_3 \)** is high only during the third interval, remaining low otherwise.
- **\( D_4 \)** remains low during the first four intervals and high for the last three.
- **\( D_5 \)** is low for the first interval, high for the next three, low for one, and high for the last two.
- **\( D_6 \)** stays low for the first two intervals, high for the next three, and low for the final two.
- **\( D_7 \)** stays high for the first five intervals and then low for the last two.

Underneath the diagram, there is a request: "Given the 8 data inputs in Figure 4, give the output waveforms for both EVEN and ODD parity."

### Explanation of Parity

- **Even Parity**: Ensures the total number of 1s in the set is even.
- **Odd Parity**: Ensures the total number of 1s in the set is odd.

By analyzing each time interval, calculate the parity bit value required for both even and odd parity.
