Abstract
Piezoelectric crystals are arranged to function as variable resonators. In one embodiment, three crystals are arranged as an array, with a center crystal between two outer crystals. An electrical excitation of the outer crystals causes a mechanical displacement in the crystals along a common axis. This displacement squeezes the center crystal, resulting in a shift of the crystal's resonant frequency. By this arrangement, signals input to the outer crystals vary the resonant properties of the inner crystal.
