Solution - Write Two Advantages of Frequency Modulation Over Amplitude Modulation. - CBSE (Science) Class 12 - Physics

Question

Write two advantages of frequency modulation over amplitude modulation.

Solution

Following are the two advantages of frequency modulation over amplitude modulation:

1)Frequency modulation is more efficient than amplitude modulation because the amplitude of an FM wave is constant, irrespective of its modulation index. Thus, the transmitted power is constant. Also, all the transmitted power is useful in FM, whereas, in AM, most of the transmitted power goes waste in the transmitted carrier.

2) FM reception is quite immune to noise in comparison to AM reception, as noise is a form of amplitude variation in the transmitted signal. Thus, by using amplitude limiters in the FM receivers, we can almost eliminate the noise.

  Is there an error in this question or solution?
