A crystal filter allows some frequencies to 'pass' through an electrical circuit while attenuating undesired frequencies. An electronic filter can use quartz crystals as resonator components of a filter circuit. Quartz crystals are piezoelectric, so their mechanical characteristics can affect electronic circuits (see mechanical filter). In particular, quartz crystals can exhibit mechanical res… WebJan 18, 2024 · The number of crystals which the filter uses is usually determined by 'the "shape factor," i.e., the required selectivity. The shape factor is a ratio of bandwidths measured at two different attenuation …
