| Abstract: | The function bwden was programmed in MATLAB environment.Writing a program to call the function in order that the denominator polynomial coefficients of Butterworth optimal transfer function could be obtained,the poles-distributing diagram,step response curve and Bode diagram of Butterworth optimal transfer function were plotted.The calculation and simulation of 8th order Butterworth optimal transfer function indicated it could be evaluated efficiently and effectively in Matlab environment. |
