WebSpectral leakage. The Fourier transform of a function of time, s (t), is a complex-valued function of frequency, S (f), often referred to as a frequency spectrum. Any linear time-invariant operation on s (t) produces a new spectrum of the form H (f)•S (f), which changes the relative magnitudes and/or angles ( phase) of the non-zero values of ...

WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. The Fourier transform of the function cos(ωt) is zero, except at frequency ±ω. However, many other functions and waveforms do not have convenient closed-form transforms. Alternatively, one might be interested in their spectral content only during a certain time period. In either case, the Fourier transform (or a similar transform) can be applied on one or more finite intervals of the wavefor…
