WebThe CWT has this windowing built in by the fact that the wavelets get shorter (in time or space) as the scale decreases (like higher frequency). Thus for higher frequencies, the effective window is shorter in duration, and you end up with a scaleogram that looks like what you have drawn for the FWT.
WebThe aim of the presented package is to obtain a time–frequency representation of the input signal for which the integrated absolute error (IAE) between its normalized marginals and the original intensities per unit time and frequency are minimal. WebTwo examples show the advantage of using the optimum representation in the time-frequency domain compared with the original time representation. Keywords. Time …
