Digital Signal Processing and Applications with the C6713 and C6416 DSK 2e

The late Rulph Chassaing , PhD, taught Real-Time DSP at Worcester Polytechnic Institute. In addition to offering many DSP training workshops and seminars, he authored four other books: DSP Applications Using C and the TMS320C6x DSK; Digital Signal Processing: Laboratory Experiments Using C and the TMS320C31 DSK; Digital Signal Processing with C and the TMS320C30; and Digital Signal Processing with C and the TMS320C25 , all published by Wiley. Donald Reay , PhD, is a Lecturer in the School of Engineering and Physical Sciences at Heriot-Watt University in Edinburgh, Scotland.
