WebFeb 8, 2024 · 1 To have good frequency resultion you need a long time series. This is a fundamental issue, called uncertainty principle. It cannot be overcome within Fourier analysis (Fourier transform, DFT, short-time Fourier transform and so on). Also note that zero padding will not overcome this issue.
