Designing Digital Filters
Design How-To 8/1/2003 2 comments
Compared to their analog counterparts, digital filters offer outstanding performance and flexibility. Designing digital filters can seem a daunting task, however, because of its seemingly endless range of implementation choices. The wide range of digital signal processing (DSP) design tools available can handle many of the details. Richard Quinnell provides the basics of filter design to get the tools jump-started.
