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:
z Measuring harmonic content and distortion in systems
z Characterizing noise in DC power supplies
z Analyzing vibration
