For introductory courses (sophomore/junior) in Digital Signal Processing and Signals and Systems. Text may be used before the student has taken a course in circuits.

This text is derived from DSP First: A Multimedia Approach, published in 1997, which filled an emerging need for a new entry-level course not centered on analog circuits in the ECE curriculum. It was also successfully used in 80 universities as a core text for linear systems and beginning signal processing courses. This derivative product, Signal Processing First [SPF] contains similar content and presentation style, but focuses on analog signal processing. Note: DSP First: A Multimedia Approach remains in print for those who choose a digital emphasis for their introductory course.
