Informationen zum Autor Donald Reay is a Lecturer at Heriot-Watt University in Edinburgh, Scotland. He has also taught hands-on DSP, on a number of occasions, as a visiting lecturer at Zhejiang University in Hangzhou, China. He coauthored, with Rulph Chassaing, the Second Edition of Digital Signal Processing and Applications with the TMS320C6713 and TMS320C6416 DSK , also published by Wiley. Klappentext This is the most comprehensive text available on hands-on teaching of Digital Signal Processing, and the first book to feature the new floating point DSP development system to be promoted by the Texas Instruments University Program: the OMAP L138 eXperimenter and CCS v4 (which replaces the C6713DSK). Using a practical approach, the book provides a large number of real-time example programs that use actual input and output signals and give visible and audible results. It is an excellent teaching aid for professors wishing to teach DSP via laboratory experiments and for students or engineers wishing to study DSP using the inexpensive OMAP L138 eXperimenter.
