Frequency Modulation (FM)
In Frequency Modulation (FM), the frequency of the carrier changes in accordance with the input analog signal, while the amplitude of the carrier remains the same. The modulated carrier contains several spectral components, requiring frequency domain analysis. The key concept and the underlying principle of FM and FM bandwidth dilemma are presented with numerous illustrations to make them easier for readers to grasp.
