Question
Answer briefly.
Why does amplitude modulation give noisy reception?
Short Note
Solution
- In amplitude modulation, the carrier is varied in accordance with the message signal.
- The higher the amplitude, the greater is the magnitude of the signal. So even if due to any reason, the magnitude of the signal changes, it will lead to variation in the amplitude of the signal. So it's easy for noise to disturb the amplitude modulated signal.
Hence, amplitude modulation gives noisy reception.
