DSP-Based Testing of Analog and Mixed-Signal Circuits [Paperback]

Answers the commonly asked questions about how digital signal processing-based machines work and what role DSP plays in the process. It shows you how DSP performs in real-test situations and uses mathematical concepts rather than derivations. The text addresses difficult test problems and their solutions resulting from the union of automatic test equipment (ATE) and DSP. The author establishes a philosophy of DSP-based testing describing how to think, how to approach a problem, how to create a solution, and how to determine if it really works properly.Preface.
