Discrete-Time Signals & Digital Filtering

This course is fundamentally concerned with the manipulation and/or synthesis of audio or other physical signals. Because we work with computers, these signals are uniformly sampled, or discretized, in time and/or space.

Discrete-Time Signals:

Digital Filtering:

Digital filters are fundamental to digital audio processing. While we only have time here for a cursory overview of the essential features of filters, students are encouraged to pursue more advanced courses and references in filter analysis and design.
