Graphical Filter Analysis
H. N. Dawirs · IEEE Transactions on Microwave Theory and Techniques · 1955
Some well known principles of filters and transmission lines are recalled and used to develop graphical methods of analyzing Iossless transmission line filters consisting of a series of symmetrical and identical sections. The results of this development are used to construct a special filter analysis chart by means of which a filter may be completely analyzed from a Smith Chart plot of the input impedance characteristics.
