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… WebThe aging of narrow and intermediate band crystal filters is almost solely dependent upon the aging of the crystals themselves. Thus, after proper conditioning, it is possible for the filters to age no more than a fraction of a part-per-million per year. This makes crystal filters ideally suited for phase-matched applications.
