frequency modulation

Frequency modulation (FM) is an instance of angle or non-linear modulation.
In this, the message signal modulates the instantaneous phase of an high frequency carrier. As
we have seen during the course of our discussion on FM in lectures, FM is much more superior
to AM in terms of power efficiency and noise immunity. These benefits come at the expense of
increased transmission bandwidth (BW) in comparison with AM. Despite not being BW efficient,
FM is widely used in radio broadcast owing to its ability to provide crystal clear sound quality.
In this lab, we shall focus on the behavior of tone modulated FM signals, followed by verification
of transmission BW computed using Carson’s rule and demodulation of FM signals
