Summary
| Description |
English: Top) A cosine signal produces a sharp peak in the corresponding powerspectrum. Middle) Shortening the time window widens that peak, and also produces high-frequency oscillations. Bottom) Windowing that signal reduces edge artifacts, and eliminates the high frequency components in the powerspectrum. |
