Filter signal processing

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
