Basic Operation

Applying a window to the YT waveform changes the waveform so that the start and stop values
are close to each other, which reduces the discontinuities.

The Math FFT function has three FFT Window options. There is a trade-off between frequency
resolution and amplitude accuracy for each type of window. You shall determine which one to
choose according to the object you want to measure and the source signal characteristics.
