1. A system for determining acceleration along a motor axis of a MEMS gyroscope comprising:

  • a processor having;

    a notch filter to remove a sinusoid from an instantaneous voltage from a motor pick up of the MEMS gyroscope;

    a memory bus for random access to data stored in a processor-readable memory; and

    a processor-readable memory in operative engagement with the memory bus, the processor-readable memory containing data including;

    a model relating at least one instantaneous voltage in a remaining instantaneous voltage to an acceleration of a proof mass along the motor axis; and

    instructions to the processor including;

    a routine to instruct the processor to compare the at least one instantaneous voltage in the model to the remaining instantaneous voltage.
