Amplitude Modulation Visualizer

This visualizer demonstrates how amplitude modulation occurs in vibration signals and how it manifests in both the time waveform and frequency spectrum.

Users can adjust the carrier frequency, modulation frequency, and modulation index to observe how sidebands form around the carrier frequency. The tool simultaneously displays the carrier signal, the modulating signal, the resulting modulated waveform, and the FFT spectrum showing the carrier and its sidebands.

This visualizer helps explain common machinery faults where modulation occurs, such as looseness, gear wear, or mechanical impacts that modulate a dominant running frequency.
