Digital vs AnalogueHardQuestion 20271

Question

Advantages of digital circuits over analogue include:
  1. A
    Lower power consumption always
  2. B
    Noise immunity — small noise doesn't flip 0/1; easy storage; reproducibility; programmability
    Correct
  3. C
    Higher frequency operation always
  4. D
    Simpler circuits for all applications

Correct answer

Noise immunity — small noise doesn't flip 0/1; easy storage; reproducibility; programmability

Explanation

Digital signals (0/1) are robust against noise because a wide margin exists between logic levels. Analogue signals degrade with every amplification stage. Digital systems are also easy to store, copy, process, and program — making them preferable for computation and communication.
