Feb 16, 2014 - In theory of FT(Fourier transform) and STFT(Short Time Fourier Transform) it is said that "A wide window gives better frequency resolution but In other words, the only thing that increases frequency resolution is time. Changes in sampling rate do nothing towards increasing the frequency resolution if theFrequency Versus Time Resolution. • Fourier analysis has high frequency resolution: – for a series of length n, the natural frequency grid is fj. = j/n. • But it has no If frequency resolution is expressed by ?f , the relationship is (1)based on the equation in 'What is the Relationship between the Time Window Length and the

Apr 8, 2013 - STFT is basically a DFT (or FFT) with sliding window. So the time-frequency resolution tradeoff is that of the DFT, that is df=1/T, with df the FREQUENCY RESOLUTION -- Obtainable frequency resolution is equal to the inverse of the time duration during which a signal is being observed, i.e., 1/T:. TIME-FREQUENCY RESOLUTION. A consequence of Fourier transforms being built from $e^{iomega t}$ is that scaling a function to be narrower in one domain Jump to Resolution issues - A wide window gives better frequency resolution but poor time resolution.
