Cascaded Integrators Comb (CIC) filter is a special class of linear phase FIR filter. It is the most simple decimation filter which does not require multipliers. Due to its simplicity, the CIC filter is usually used in the first stage of decimation. They are used in multi-rate digital signal processing systems which have different applications such as efficient filtering, sub band loading, analogue / digital conversions, audio video signals. However the filter exhibits a high pass band droop which is inacceptable in different application. In this paper, the improvement in pass band droop is done by zero rotation approach.
