Signal Processing
ABSTRACT
In an electronic system when a signal goes around from sensor to the microcontroller or
from the microcontroller to a motor driver, there is always noise in the system. A small
noise will cause errors, so it should be filtered. The filters are designed depending on the
signal frequency. Fourier Transform is the mathematical basis of the filtering and linear-
ization of the signals. This methodology basically explains how any complex signal is
made up from the combination of simple signals.
