1. A method for signal conditioning in an electronic sensor having a sensing element, the sensing element generating a first signal and a second signal, the method comprising the steps of:

  • receiving the first signal from the sensing element, the first signal having a frequency at an event;

    sampling the second signal from the sensing element based on the frequency of the event, the second signal having a plurality of components, one of the plurality of components being a first component of interest;

    generating a synchronized second signal in a time domain, the second signal having the plurality of components;

    generating complex data in a frequency domain from the synchronized second signal in the time domain;

    determining the first component of interest from the complex data; and

    normalizing the first component of interest using amplitude information from the first signal.
