Analysis of FFT frequency spectrum

Time domain signal can be converted to frequency
domain signal when using mathematical calculation
of fast Fourier transtable (FFT). Following types of
signals can be observed conveniently by using
FFT
Measure harmonic content and distortion within
measurement system;
Show noise characteristics in DC power;
Analyze vibration;
