Crystal filter theory
WebThe universal crystal filter is a lattice circuit. The lattice is usually developed in full "four-arm" form (i.e., as a bridge circuit) and then the equivalence of the half-lattice is proved. The reader is referred to … 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…
