Taajuuspehmennystä
Taajuuspehmennystä, known in English as frequency smoothing or spectral smoothing, is a signal processing technique used to reduce noise or unwanted fluctuations in data that has been transformed into the frequency domain. This transformation often occurs after applying a Fourier Transform to time-domain data, resulting in a spectrum that shows the amplitude or power of different frequencies present in the original signal.
The raw frequency spectrum can be quite jagged due to random noise or artifacts. Taajuuspehmennystä aims to
The application of taajuuspehmennystä is widespread in fields like audio processing, where it can smooth the
