Webb2 maj 2024 · The Windowing Technique, in which the windowing function is multiplied with the desired frequency response, helps minimize the effects of these oscillations giving us a more desirable output from the truncation of the IIR filter. Windowing But how do you determine the frequency range to ensure you design an effective filter. Webb8 feb. 2014 · This causes the ripple on either side of the peak that you see. The hamming window reduces this ripple, giving you a more accurate idea of the original signal's frequency spectrum. More theory, for the interested: when you cut your signal off at either end, you are implicitly multiplying your signal by a square window.
