Acceleration effects in crystal filters-a tutorial.
The quasi-static method for the analysis of vibration-induced modulation in crystal filters is briefly reviewed, and a dynamic method, in which the filter is treated as a linear network with time-varying elements, is introduced. The dynamic method, which allows determination of both amplitude and phase modulation due to vibration, is illustrated by examples. It is then applied to the analysis of the spectrum clean-up case, consisting of a frequency source with an output filter, both of which are undergoing the same acceleration.
