Using FFT function

The FFT (Fast Fourier Transform) process converts a time-domain signal into its

frequency components mathematically. FFT waveforms are useful in the following

applications:

Measuring harmonic content and distortion in systems

Characterizing noise in DC power supplies

Analyzing vibration
