Abstract:The thesis proposes a new method synthesizing the generalized Chebyshev LC filters, whose transmission zeros can be set freely and outer sides rejection can be symmetrical or asymmetrical. A LC filter can be synthesized with this method. Its ripple performance of pass-band is as good as that of Maximally Flat filter and its rejection of outer side is as good as that of Elliptic filter. Every transmission zero of generalized Chebyshev LC filters can be controlled by only one component. Compared with Elliptic LC filters, generalized Chebyshev LC filters can get better outer sides rejection with the same number of components.
