Crystal filter shape factor
WebIt seemed likely that a measurement of a linear dimension together with a factor describing the shape of the particles would be the most useful parameters to correlate with filter … 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…
