What does an FFT analyzer do?
The FFT spectrum analyzer samples the input signal, computes the magnitude of its sine and cosine components, and displays the spectrum of these measured frequency components.
What is Fast Fourier Transform used for?
The FFT is used to process data throughout today's highly networked, digital world. It allows computers to efficiently calculate the different frequency components in time-varying signals—and also to reconstruct such signals from a set of frequency components.
Is Spectrum Analyzer the same as FFT?
Fourier (or FFT) analyzers
The Fourier or FFT spectrum analyzer is another real-time spectrum analyzer implementation. The Fourier analyzer, also referred to as a dynamic signal analyzer, use digital signal processing to sample the input signal and convert it to the frequency domain.
