Waveform and Spectrum Visualizer

This visualizer demonstrates the relationship between a vibration time waveform and its frequency spectrum. The tool allows users to generate vibration signals composed of multiple sinusoidal components and observe how those components appear in both the time domain and frequency domain.

Users can adjust the frequencies and amplitudes of the individual signal components and instantly observe how the combined waveform changes. The Fast Fourier Transform (FFT) of the signal is calculated and displayed to show how each frequency component appears in the spectrum.

The visualizer also allows users to modify parameters such as spectral resolution and frequency limits, illustrating how these settings influence FFT interpretation.

Because many analysts learn FFT interpretation only from static spectra, this visualizer provides an intuitive way to understand how vibration signals are constructed and how those signals translate into spectral peaks.
