The Dishal procedure is described in "Randall W. Rhea: HF filter design and computer simulation" Mc Graw-Hill ISBN 0-07-052055-0 pages 392-394 Everyone doing practical filter design should have this book. Rhea has also a good oscillator design book and is the author of that what evolved to Eagleware / Agilent Genesys. (has nothing to do with the Eagle layout program) Genesys also has a nice filter design plugin. regards, Gerhard
