(A) : Digital signals are preferred to analog signals for transmission of information.
(R) : Analog signals require amplification and correction at suitable intervals.

Options

A. Both 'A' and 'R' are true and 'R' is the correct explanation of 'A'.
B. Both 'A' and 'R' are true and 'R' is not the correct explanation of 'A'.
C. A' is true abd 'R' false
D. A' is false and 'R' is false

Answer

To analyze the given statements, we will break down the assertion and the reason step by step.

### Step 1: Understanding the Assertion
**Assertion (A)**: Digital signals are preferred to analog signals for transmission of information.

- **Explanation**: Digital signals are preferred because they can be transmitted over long distances with less distortion. They are more robust against noise and interference compared to analog signals. This makes them suitable for various communication systems, including telecommunication and broadcasting.

### Step 2: Understanding the Reason
**Reason (R)**: Analog signals require amplification and correction at suitable intervals.

- **Explanation**: Analog signals are continuous and can degrade over distance due to noise and interference. As a result, they often need to be amplified and corrected periodically to maintain signal quality. This requirement for frequent adjustments makes analog signals less efficient for long-distance transmission compared to digital signals.

### Step 3: Evaluating the Truth of Both Statements
- **Truth of Assertion (A)**: True. Digital signals are indeed preferred for transmission due to their advantages over analog signals.
- **Truth of Reason (R)**: True. Analog signals do require amplification and correction at intervals to maintain quality.

### Step 4: Analyzing the Relationship Between A and R
- **Does R explain A?**: While both statements are true, the reason (R) does not directly explain why digital signals are preferred over analog signals. The preference for digital signals is due to their ability to maintain integrity over long distances, not solely because analog signals require correction.

### Conclusion
- Both the assertion (A) and the reason (R) are true.
- However, the reason (R) is not the correct explanation for the assertion (A).

### Final Answer
Both A and R are true, but R is not the correct explanation of A.
