Generation of FM signal
In frequency modulation,
a) Armstrong method is used for generation
b) Multiple side bands are generated
c) The FM signal has infinite bandwidth
d) All of the above
Correct Answer: d) All of the above
Armstrong method is used for the generation of FM signal. The FM signal has a high quality of audio signal and reduced noise as compared to the AM wave. In FM, multiple side bands are generated therefore has infinite bandwidth though only the first few sets of sidebands are useful for detection of signal.
