| Abstract: | The discretization problem of Chebyshev filter is addressed in this paper. Considering the order, sampling rate, cross frequency, disretization method and filter style, a detailed comparing analysis is given, and two solutions to that problem is also proposed. Finally, simulation example and one experiment results are given to prove the effectiveness of the proposed methods |
