Question

The primary advantage of digital communication over analog is:
  1. A
    Always lower bandwidth
  2. B
    Better noise immunity and regeneration (no noise accumulation)
    Correct
  3. C
    No need for modulation
  4. D
    Lower transmitter power in all cases

Correct answer

Better noise immunity and regeneration (no noise accumulation)

Explanation

Digital signals can be regenerated — noisy 0s and 1s are detected and retransmitted as clean pulses. Analog amplifiers amplify noise along with the signal. Digital also enables error correction, encryption, and compression.
