1. A signal processing method for removing noise from a signal comprising:
establishing at least first and second sample rates with the second sample rate higher than the first;
establishing at least first and second degrees of smoothing with the second degree less than the first degree;
sampling a signal at the first rate;
smoothing the sampled signal with the first degree of smoothing;
evaluating a first smoothed, sampled signal value, and
where the first value crosses a threshold value, altering both the sample rate and the degree of smoothing for a predetermined time interval.
