(ebook) practical fir filter design in matlabPractical FIR Filter Design in MATLAB R Revision 1.1 Ricardo A. Losada The MathWorks, Inc. 3 Apple Hill Dr. Natick, MA 01760, USA January 12, 2004 Abstract This tutorial white-paper illustrates practical aspects of FIR lter design and xed-point implementation along with the algorithms available in the Filter Design Toolbox and the Signal Processing Toolbox for this purpose. The emphasis is mostly on lowpass lters, but many of the results apply to other lter types as well. The tutorial focuses on practical aspects of lter design and implementation, and on the advantages and disadvantages of the different design algorithms. The theory behind the design algorithms is avoided except when needed to motivate them. 4 Optimal equiripple designs with xed transition width and peak passband/stop……
