Fourier Transform Intuition

Harmonic Analysis is fundamental for power quality investigation, revealing information about a power signal by examining frequency domain multiples of the 60 Hz line frequency. The Fast Fourier Transform (FFT) is key to calculating this harmonic data. Beyond power quality, FFT is widely used in signal processing industries like communications, image compression, physics, audio, radar, and mechanical vibration. This white paper aims to demystify FFT, making it a practical tool.
