medium Q5 of 15
General Science - Physics (Basics)
Which of the following is NOT a feature of analog communication?
AContinuous signal variation
BSusceptible to noise and distortion
CEasier to encrypt and compress
DSignal amplitude varies smoothly
Step-by-Step Solution
  1. Step 1: Recall characteristics of analog communication

    Analog signals vary continuously and smoothly but are more prone to noise and distortion.
  2. Step 2: Identify incorrect feature

    Encryption and compression are easier in digital communication, not analog.
  3. Final Answer:

    Easier to encrypt and compress → Option C
  4. Quick Check:

    Analog communication = Difficult to encrypt/compress ✅
Quick Trick: Encryption/compression easier in digital, not analog
Common Mistakes:
  • Assuming analog signals are easy to encrypt or compress.
