www.analog.comdemodulated (demod). The modulation technique is independent from the receiver technology. The modulation scheme could be amplitude modulation (AM), frequency modulation (FM), phase modulation or some form of quadrature amplitude modulation (QAM), which is a combination of amplitude and phase modulation.
Chapter 8 Frequency Modulation (FM) Contents
user.eng.umd.eduwhere ∆f is the peak frequency deviation and fm is the maximum baseband message frequency component. Example Commercial FM signals use a peak frequency deviation of ∆f = 75 kHz and a maximum baseband message frequency of fm = 15 kHz. Carson’s rule estimates the FM signal bandwidth as BT = 2(75+15) = 180 kHz which is six times
