Why Use DSP?
Digital Signal Processing 101 An introductory course in DSP system design: Part 1 Also see: (Part 2) (Part 3) (Part 4) by David Skolnick and Noam Levine Having heard a lot about digital signal processing (DSP) technology, you may have wanted to find out what can be done with DSP, investigate why DSP is preferred to analog circuitry for many types of operations, and discover how to learn enough to design your own DSP system. This article, the first of a series, is an opportunity to take a substantial first step towards finding answers to your questions. This series is an introduction to DSP topics from the point of view of analog system designers seeking additional tools for handling analog signals. Designers reading this series can learn about the possibilities of DSP to deal with analog signals and where to find additional sources of information and assistance. What is [a] DSP? In brief, DSPs are processors or microcomputers whose hardware, software, and instruction sets are optimize
