7 CONCLUSION
In conclusion, Frequency Modulation (FM) stands as a
fundamental modulation technique in the realm of
communication systems, allowing us to transmit information
over the airwaves with enhanced resilience to noise and
interference. By varying the frequency of a carrier signal in
proportion to the amplitude of the modulating signal, FM
enables the encoding of data in the form of frequency
deviations.
