This is a comprehensive introduction to digital signal processing, a growing and important area for the aspiring electronics or communications engineer. The aim of the book is to provide an introduction to the fundamental DSP operations of filtering, estimation and analysis. The book will be supported with a website of MATLAB experiments. Lecturer support will also be available via an on-line solutions manual (available via a password). Hardcopy solutions are also available. This work is intended primarily for undergraduate electrical/electronic/communications engineers, but should also be useful for some professional "short courses" that bring engineers educated only in analogue techniques up to scratch in the digital world.
