| Abstract: | The thesis introduces the elementary theory and the design thoughts of digital ellipse filter,and how to design it.It takes band pass filter for example to express the realization of the digital ellipse filter through on Matlab.We can conclude that it is easy and direct viewing to design the digital ellipse filter.In the end,it compares the function of Butterworth filter,Chebyshev filter and ellipse filter. |
