Let’s Clear Up Some Things About FFT…

Part 1 of 2: The basics

The "Fast Fourier Transformation" (FFT) is an important measurement method in science of audio and acoustics measurement. It converts a signal into individual spectral components and thereby provides frequency information about the signal. FFTs are used for fault analysis, quality control, and condition monitoring of machines or systems. This article explains how an FFT works, the relevant parameters and their effects on the measurement result.
