WU Jia-fu · Journal of Jiyuan Vocational and Technical College · 2010
Being computer software,MATLA is mainly used in matrix operations and control and analysis design in the field of information process.As one excellent algorithmic research and computer-aided design tool,signal processing toolbox,which includes different classic and modern digital process technology,is one of the functions of MATLA.Adopted bilinear method,IIR filter is designed.Based on filter index,Butterworth digital filter rank number and frequency parameter is achieved and IIR digital filter is designed through design function provided by MATLAB.When the parameter of digital filter is got based on the design,the original editing program can be achieved on DSP.
