Abstract

Determining transmission zeroes is the important precondition in the synthesis of the cross‐coupled filter. A novel method to determine the general Chebyshev filter degree and transmission zeroes at the same time is proposed, according to the extreme characteristic of the general Chebyshev function and the relationship between the filter degree and the number of transmission zeros. On the condition of given filter specifications, the least filter degree and the optimum positions of transmission zeroes are realized. Several application examples illustrate the procedure and the validity of the proposed method. Β© 2007 Wiley Periodicals, Inc.
