Elaboration of Algorithm for Computer Aided Optimization of Band-Pass Networks

This paper is focused on applications of the first and second Norton's transform in optimization of bandpass filters. Norton's transforms are practiced primarily in the final adjustment of filter design. An optimization procedure of filter synthesis can be based on different aspects and circuit requirements. The special design and optimization software for band-pass network was written in Borland C++ Builder 6, and that is discussed in the paper. This program allows the design of band-pass filter up to twentieth order with more repetition of Norton's transform in synthesized circuit including graphic and printing output.
