    In particular, quartz crystals can exhibit mechanical resonances with a very high Q factor (from 10,000 to 100,000 and greater — far higher than conventional resonators built from inductors and capacitors). The crystal''s stability and its high Q factor allow crystal filters to have precise center frequencies and steep bandpass characteristics.

  • Filter (signal processing) Wikipedia

    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
