Vedclass · Answer

(B) In communication systems,noise primarily affects the amplitude of the signal. Frequency Modulation $(FM)$ is generally more noise-tolerant than Amplitude Modulation $(AM)$. Among the given options,$Short-wave$ signals (often associated with specific propagation characteristics and modulation techniques) are historically recognized for better performance in long-distance communication compared to $Long-wave$ or $Medium-wave$ signals,which are more susceptible to atmospheric noise and interference.

Which of the following modulated signals has the best noise tolerance?
