Question
Given the timing diagram below, construct a truth table and write the equation for the function as POS (Product of Sums).

The diagram consists of four input signals labeled A, B, C, and D. Each signal transitions between high and low states over 16 sample intervals. The output is depicted as F(A, B, C, D).

### Timing Diagram Details:
- **A**: High (0-1), Low (2-3), High (4-5), Low (6-7), High (8-9), Low (10-11), High (12-15)
- **B**: High (0-1), Low (2-3), High (4-7), Low (8-9), High (10-11), Low (12-13), High (14-15)
- **C**: High (0), Low (1), High (2-3), Low (4-5), High (6-7), Low (8-9), High (10-11), Low (12-13), High (14-15)
- **D**: High (0), Low (1-2), High (3-4), Low (5-6), High (7-8), Low (9), High (10), Low (11-12), High (13-14), Low (15)

### Constructing the Truth Table:
The truth table will have columns for A, B, C, D, and F, with F representing the output at each sample point. The values will depend on the high or low state of each input signal at each sample interval.

### Writing the Equation:
To express the equation as a Product of Sums (POS), identify the conditions where the output F is low (0), and write a sum term for each. The final POS expression is a product (AND) of these sums (ORs).

> This exercise requires examining each sample point (0-15) to determine the output values and constructing the truth table and corresponding POS equation accordingly.
