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.
