In amplitude modulation (AM), the amplitude of the carrier changes in accordance with the input analog signal, while the frequency of the carrier remains the same. The modulated carrier contains several spectral components, requiring frequency domain analysis. In an effort to examine this, this ...
Amplitude modulation can be represented by this equation where fc is the carrier, fm is the modulation frequency and m is the depth of modulation, also referred to as the modulation index. The depth of modulation is defined as the ratio of the peak of the modulating signal to the peak of...
