Designing the FIR filter by MATLAB can simplify the complicated computation in simulation and improve the performance. By using the methods of window function, frequency sampling and convex optimization techniques, the design of FIR filter has been processed by MATLAB. In the view of the designed ...

There are following problems in filter design using window method: (i) This method is applicable only if Hd(w) is absolutely integrable i.e only if (2) can beevaluated. When Hd(w) is complicated or cannot easily be put into a closed form mathematical expression, evaluation of hd(n) bec...
