In signal processing, a filter is a device or process that removes some unwanted components or features from a signal. Filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of the signal. Most often, this means removing some frequencies or frequency bands. However, filters do not exclusively act in the frequency domain; especially in the field of image processing many other targets for filtering exist. Correlati… WebMay 14, 2024 · If our signals are sufficiently long we can compute their discrete Fourier transforms (DFTs) using the Fast Fourier Transform (FFT) algorithm.
