FFT

The FFT function performs a Fast Fourier Transform (FFT) to convert the input payload between time and frequency domains.

The Function can perform the transform in either direction: forward or backward.

Forwards

From a time-domain representation to a frequency-domain representation. Use this option to determine how much of the signal lies within each frequency band across a range of frequencies

Backwards

From a frequency-domain representation to a time-domain representation. Use this option to determine how a signal changes over time, given the distribution of the frequencies of its component sine waves.

Details for an example and its configuration can be found in the How to Use section.

This Agent expects to receive batched data. There is no effect on events received singly.
