Beating Visualizer

The beating visualizer illustrates what happens when two similar frequencies interact. When two signals with slightly different frequencies combine, they produce a waveform whose amplitude fluctuates at the difference between the two frequencies.

Users can adjust the two frequencies and observe the resulting time waveform, which shows the characteristic “beating” envelope. The beat frequency and beat period are also displayed to demonstrate the relationship between the two source frequencies.

This concept is important in vibration analysis because beating can appear when multiple rotating components have similar speeds or when spectral peaks are closely spaced.
