WebJun 29, 2007 · Meanwhile, FFT-based analyzers have no analog filter and instead useFFT and its associated windowing parameters to determine frequencyresolution or RBW. Current FFT-based analyzers, unlike traditionalspectrum analyzers, can offer a choice of windows to limit spectralleakage and improve resolution of closely spaced tones in the … Weblimitations of the FFT and how to improve the signal clarity using windowing. a. What Is Windowing When you use the FFT to measure the frequency component of a signal, you are basing the analysis on a finite set of data. The actual FFT transform assumes that it is a finite data set, a continuous spectrum that is one period of a periodic signal.
