Question

Why is frequency modulation preferred over amplitude modulation for transmission of music?

Advertisements

Solution

Frequency modulation gives a better quality of transmission because it has a larger bandwidth and is relatively immune to noise. The transmission of information of FM signal is in the form of frequency variations. Therefore, the atmospheric noise causes little harm to it. Frequency modulation is, therefore, preferred over amplitude modulation for transmission of music.

In amplitude modulation, the modulation index m, is kept less than or equal to 1 because ______.

  1. m > 1, will result in interference between carrier frequency and message frequency, resulting into distortion.
  2. m > 1 will result in overlapping of both side bands resulting into loss of information.
  3. m > 1 will result in change in phase between carrier signal and message signal.
  4. m > 1 indicates amplitude of message signal greater than amplitude of carrier signal resulting into distortion.
