Give the definition of am and fm. Why fm reception is immune to noise

Answers

Answered by vanijamathur

Answer:

AM stands for Amplitude Modulation

FM stands for Frequency Modulation

The change in amplitude can modulate the signal and can be picked up in an AM system. FM systems are inherently immune to random noise. For noise to interfere in FM, it will have to modulate the freq somehow but noise is distributed uniformly, in freq and varies mostly in amplitude. So FM is more immune to noise.
