A method for extracting components from signals in an electronic sensor (50)
having a sensing element (52). The sensing element (52) generates
a first signal (60) and a second signal (62). The method comprises
the steps of: receiving the first signal (60) from the sensing element (52),
the first signal (60) having a frequency at an event; sampling the second
signal (62) from the sensing element (52) based on the frequency
of the event, the second signal (62) having a plurality of components, one
of the plurality of components being a first component of interest (112, 114);
generating a synchronized second signal (100) in a time domain, the second
signal (62) having the plurality of components; generating complex data
(110) in a frequency domain from the synchronized second signal (100)
in the time domain; determining the first component of interest (112, 114)
from the complex data (110); and normalizing the first component of interest
(112, 114) using amplitude information from the first signal (60).
