Why is frequency modulation preferred over amplitude modulation for transmission of music?
Asked by Topperlearning User | 09 Jul, 2014, 10:49: AM
answered-by-expert Expert Answer

F.M. transmission gives higher fidelity reception than A.M. transmission due to the presence of a large number of sidebands. FM reception is quite immune to noise as compared to AM reception.
