Using the FFT
The FFT process mathematically converts a time-domain signal into
its frequency components. FFT waveforms are useful in the
following applications:
 Testing impulse response of filters and systems
 Measuring harmonic content and distortion in systems
 Characterizing noise in DC power supplies
 Analyzing vibration
 Analyzing harmonics in 50 and 60 Hz power lines
There are five steps to using the FFT:
1. Set up the source (time-domain) waveform
2. Display the FFT waveform
3. Select the FFT window type
4. Adjust the sample rate to display fundamental frequency and
harmonics without aliasing
5. Use zoom controls and the cursors to magnify and measure the
FFT waveform
