Abstract :
The research uses the FDA tool of MATLAB
to consider and show the design of a decimation filter
with three stages. The decimation filter lowers the
signal's sampling rate while maintaining the necessary
data. Since the single stage filter is particularly
challenging to build and has poor frequency response
due to the need for more coefficients, three stages of
filters are taken into consideration. In filter design, a
CIC filter is taken into account in the first stage,
followed by FIR filters in the following two stages, which
are decimated after each stage.
Keywords :
Decimation filter, Decimation factor, CIC filter, FIR filter.
