Design and Realization of Digital FIR Filter using Dolph-Chebysheb Window
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2013, Vol 4, Issue 7
Abstract
In Digital Signal Processing, one of the most important filter type is the FIR filter which can be designed via various methods. Window technique is the most important technique that is used to design the FIR filter. Apart from various window techniques, Dolph-Chebyshev window has the subject of importance for the design of the FIR filter in efficient way. In this paper, the design methodology of the FIR filter using Dolph-Chebyshev window is shown along with the realization of filter and the designing algorithm. The designing program of the FIR filter is simulated in Matlab 7 which shows the satisfactory result. In this paper, the minimization of the side lobes using Dolph-Chebyshev window are shown and can easily be understood that the minimization in side lobes can increase the efficiency and decrease power consumption so that the FIR filter can work more efficiently.
