1. A method of decoupling a drive signal from a pickoff signal to attenuate the effect of electrical cross-coupling between the drive signal and the pickoff signal, the method comprising:

  • providing a drive signal at a first frequency that is represented by a plurality of data values;

    altering at least one of the plurality of data values of the drive signal; and

    producing a pickoff signal at a second frequency different from the first frequency of the drive signal;

    whereby the pickoff signal is distinguished from any cross-coupled drive signal.
