AIt compresses the audio file size
BIt converts sound into light signals
CIt measures the sound wave at regular intervals
DIt removes background noise automatically
Step-by-Step Solution
Solution:

  1. Step 1: Understand sampling in audio digitization

    Sampling means taking measurements of the sound wave at fixed time intervals to capture its shape.

  2. Step 2: Identify the correct description

    Measuring the sound wave regularly matches the definition of sampling, unlike compression or noise removal.

    It measures the sound wave at regular intervals -> Option C

  4. Quick Check:

    Sampling = Measuring sound wave [OK]
Quick Trick: Sampling means measuring sound at set times [OK]
Common Mistakes:
MISTAKES
  • Confusing sampling with compression
  • Thinking sampling removes noise
  • Believing sampling converts sound to light
