In many communication and signal processing
systems, it is highly desirable to implement an efficient narrowband
filter that decimate or interpolate the incoming signals. This paper
presents hardware efficient compensated CIC filter over a narrow
band frequency that increases the speed of down sampling by using
multiplierless decimation filters with polyphase FIR filter structure.
The proposed work analyzed the performance of compensated CIC
filter on the bases of the improvement of frequency response with
reduced hardware complexity in terms of no. of adders and
multipliers and produces the filtered results without any alterations.
CIC compensator filter demonstrated that by using compensation
with CIC filter improve the frequency response in passed of interest
26.57 with the reduction in hardware complexity 12.25
multiplications per input sample (MPIS) and 23.4 additions per
input sample (APIS) w.r.t. FIR filter respectively.
