Assertion : In a communication system based on amplitude modulation...

Assertion : In a communication system based on amplitude modulation the modulation index is kept <1< 1. Reason : It ensures minimum distortion of signal.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

A. If both assertion and reason are true and reason is the correct explanation of assertion.

Step-by-step solution

The modulation index in practice, is kept ≤1\leq 1 to avoid distortion.
