Abstract
With the development of more compact and efficient ways of implementing digital logic on a silicon chip, most of the signal processing is being performed in the digital domain. The design of an efficient configurable digital decimation filter is focused in work. The Cascaded Integrator-Comb (CIC) filters are used as decimation filter. The five stage CIC filter is proposed in this paper. It does not require any multiplier circuit and also uses recursive or non-recursive filter[4]. CIC is the combination of equal number of Integrator and comb stages . The CIC filter is based upon a low-pass filtration system .These types of filter systems are utilized within the decimation that has the result upon decreasing the actual sample rate. The result of CIC filter impulse and magnitude response exposed using of MATLAB
