When a resonator experiences an
acceleration, the strains due to the acceleration cause frequency changes, as
shown above. Under vibration, the time
varying strains cause time dependent frequency changes, i.e., the vibration
causes frequency modulation, as shown on the pages that follow.

The relationship between frequency and
acceleration can become nonlinear at high accelerations due to deformation of
the mounting structure. The
acceleration sensitivity can also be a function of temperature.
