Use Filter Designer with DSP System Toolbox Software. This paper describes decimation process by the focus on high speed implementation of CIC filter (Hogenauer EB 1981). The Matlab filter function filters the input data x using a rational transfer function defined by the numerator and denominator coefficients b and a and initial conditions z. Note, with multi-rate filters you only want to use the "usable" spectrum after decimation. In figure 2, the input x(n) and the coefficient bi are 8-bits signed. Single stage CIC filte r and multistage CIC filters are realized. In this example, you designed three individual interpolation filters, cascaded them into a Digital-Up Converter, verified the frequency response of the filter, and called Filter Design HDL Coder™ functions to generate VHDL code for the filter and a VHDL test bench to verify the VHDL code against its MATLAB result. compensation fir filter design. Once the functionality of the filter is verified, the Verilog coding for the filter will be written, simulated and compared with the results. The output are four subfigures shown in the same figure: Subfigure 1: The initial noise free "lena" Subfigure 2: The noisy "lena" Subfigure 3: Filtered the initial "lena" Subfigure 4: Filtered the noisy "lena".
