Personal computer support for teaching analog filter analysis and design

A computer-aided design (CAD) program for analog filter synthesis, FILTER, which enhances the effectiveness of teaching analog filter analysis and design, is described. Initially, FILTER was developed to support related courses in the Department of Electrical Engineering at the University of Wyoming, but eventually its scope went beyond that intent. This program very effectively fills the gap between textbooks, and professional programs, which are not designed for educational use. Essential features of an educational computer program in this field are considered and these requirements are fulfilled in FILTER. The paper can serve as a guide for the reader to launch FILTER and browse through it for the first time with almost no effort.<
