This report describes the development of a Drexel University electrical and computer engineering course on digital filter design that used interactive computing and graphics, and was one of three courses in a senior-level sequence on digital signal processing (DSP). Interactive and digital analysis/design routines and the interconnection of these routines into a digital filter analysis/design package for computer assisted instruction (CAI) are discussed. Five examples illustrate the educational approach to integrating a software package into digital filter design coursework. The first two examples use a program based on the relationship between the pole-zero pattern of a given transfer function and its dynamic response. The design of digital filters from standard Butterworth and Chebyshev analog filters using the bilinear transform is explored in the third example, and the fourth and fifth examples illustrate the use of the computer aided methods proposed by Steiglitz and McClellan and Parks. A discussion of results based on a questionnaire survey of 68 students indicates that the CAI approach is effective in DSP. A majority of the students found the programs to be a worthwhile supplement to the course. Nineteen references are listed. (LMM)
