Crystal phasing filter
Webbandwidth, a very high impedence. In a single crystal filter circuit (see diagram on the next page), a variable capacitor is used to neutralize the capacitance of the crystal holder and in use, this ‘phasing’ can be used to enhance a wanted or reject an unwanted signal close in frequency to the desired signal (up to 45db of 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…
