Digital Filter Design Part 1: Frequency Response Review and Design Criteria
This set of videos provides a short introduction to digital filter design. We start by reviewing the concept of a system Frequency Response and work a variety of example problems. Then, we learn how to design filters by placing poles and zeros in the Z-domain. Finally, we introduce a time-domain criteria and a frequency-domain criteria that can be used to transform a continuous-time filter into an equivalent discrete-time filter.
