COURSE # TOO-320
DIGITAL SIGNAL PROCESSING (DSP) - PRINCIPLES, ARCHITECTURES, AND SYSTEM APPLICATIONS
Comprehensive, application-driven presentation of the technology, benefits and limitations of Digital Signal Processing with special emphasis on communications systems.
Modern communications systems offering voice, data, and multimedia services draw heavily on sophisticated signal processing. Rapid advances in microelectronics, computer architecture, and software tools have created opportunities to address these needs with cost-effective, high performance Digital Signal Processors.
This course introduces DSP technology in the context of system level concepts and considerations, and emphasizes specific functions that are ideally suited for DSP implementations. The course has been developed with all those in mind who want a simple-to-understand, practical, yet comprehensive introduction to the technology. While DSP technology and the information provided in this course are applicable to a wide variety of systems, communications systems , and digital wireless communications systems in particular, serve as the instructional vehicle.
Applications and benefits:
You will benefit by enhancing your understanding of the:
- Communications Systems, particularly as they lend themselves to DSP implementations.
- DSP Architectures.
- Practical application of DSP to real world problems.
- Limitations of DSP processors and DSP techniques.
Who should attend:
This course presents an introduction, overview and application considerations of Digital Signal Processing. It has been developed as an introduction and information resource for Technical Managers, Systems Engineers, Product Planners, and Hardware/Software Developers who are considering DSP as a component of their systems, or who must interface with DSP subsystems. Participants in this course will obtain practical information about communications systems.This course has no prerequisites; however, prior technical training in engineering, sciences or equivalent experience will be helpful.
