ABSTRACT:
A method for adjusting the frequency of a piezoelectic resonator such as a quartz crystal is disclosed. The resonator is placed within its enclosure facing a metallic surface. The atmosphere within the enclosure is made suitable for supporting a glow discharge. An electrical potential is then established between the resonator electrode and the metallic surface causing mass to sputter between the electrode and to the metallic surface to vary the characteristics of the resonator.
