Filter (signal processing) - Wikipedia
https://en.wikipedia.org/wiki/Filter_(signal_processing)
WEBIn 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.

Filtration - Wikipedia
https://en.wikipedia.org/wiki/Filtration
WEBFiltration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated. Filtration, as a physical operation enables materials of different chemical compositions to be separated.

WEBAug 20, 2019 · Before filtering the mixture, allow the solid to settle to the bottom of the beaker. Then carefully decant (pour off liquid leaving solid in container) the supernatant liquid through the filter. This is done to prevent early accumulation of precipitate on the filter paper which would slow the filtration process.

WEBApr 28, 2017 · Filtration is the separating of substances based on their different physical and chemical qualities. Typically, we think of it as the removal of solid particles from a mixture containing both solids and liquids. In this process, we refer to the collected solid material as the residue and the fluid material as the filtrate.

WEBSep 30, 2023 · A filter is a circuit capable of passing (or amplifying) certain frequencies while attenuating other frequencies. Thus, a filter can extract important frequencies from signals that also contain undesirable or irrelevant frequencies. In the field of electronics, there are many practical applications for filters. Examples include:
