26、d(n) by the rectangular window defined as w(n) = 1 0nM-1 (4)0 otherwiseThus the unit sample response of the FIR filter becomes h(n) = hd(n) w(n) (5) = hd(n) 0nM-1= 0 otherwise Now, the multiplication of the window function w(n) with hd(n) is equivalent to convo...
The filter has been designed and simulated using Matlab 7.6. Resultsshow that performance of Blackman Hanning window techniques are better as compared to Rectangular, Hamming andBartlett. Performance has been further improved using Kaiser and Equiripple window methods. Equiripple window basedFIR filter ...
Window function can be divided into 9、six kinds of window functions, respectively, for the rectangular window, triangular window, Hamming window, Hamming window, Blackman window and Kaiser window. This report implements using the window function method to design the FIR filter in the MATLAB ...
