Frequency Modulation Techniques Explained by G SOMESHWAR RAO is a document available to read on EtoBox.

1. Frequency modulation (FM) is a type of angle modulation where the frequency of the carrier wave is varied according to the message signal. In FM, the instantaneous frequency changes with the instantaneous amplitude of the message signal. 2. For single tone FM, the FM signal equation is s(t) = AC cos[2πfC t + βsin(2πfm t)], where β is the modulation index which determines if the FM is narrowband (β < 1) or wideband (β > 1). 3. In narrowband FM, the signal can be expressed as the sum of the carrier and
