ADVANTAGES OF FREQUENCY MODULATION OVER AMPLITUDE MODULATION

The syllabus for class XII Physics of CBSE mentions this point and it is not given in NCERT book. 


The advantages of AM radio - it is relatively easy to detect with simple equipment, even if the signal is not very strong. The other advantage is that it has a narrower bandwidth than FM, and wider coverage compared with FM radio. 
The major disadvantage of AM is that the signal is affected by electrical storms and other radio frequency interference. 
A distinct advantage that FM has over AM is that FM radio has better sound quality than AM radio. The disadvantage of FM signal is that it is more local and cannot be transmitted over long distance. Thus, it may take more FM radio stations to cover a large area. Moreover, the presence of tall buildings or land masses may limit the coverage and quality of FM. Thirdly, FM requires a fairly more complicated receiver and transmitter than an AM signal does.

ALL THE BEST!!!
