A digital signal possesses

Options

A. continuously varying values
B. only two discrete values
C. only for discrete values
D. none of the above

Answer

### Step-by-Step Solution:

1. **Understanding Digital Signals**:
- Digital signals are a type of signal that represent data as discrete values. Unlike analog signals, which can take any value within a range, digital signals only take specific values.

2. **Binary Nature of Digital Signals**:
- Digital signals are often referred to as binary signals. This is because they operate using two distinct states.

3. **Discrete Values**:
- The two discrete values that a digital signal can possess are typically represented as '0' and '1'.
- In electronic terms, these correspond to low (0) and high (1) voltage levels.

4. **Conclusion**:
- Therefore, a digital signal possesses only two discrete values: 0 and 1. This characteristic is fundamental to digital communication and processing.

5. **Final Answer**:
- The correct answer is: A digital signal possesses only two discrete values.
