Analog and Digital Signal Processing

This textbook on signals and systems provides a complete array of MATLAB tools specifically designed for the course, compatible with MATLAB 3.5 or 4.0. This software tool is used in the context of a thorough presentation of systems concepts and analysis techniques at an appropriate level for electrical engineering undergraduates. Use of MATLAB helps students to understand what the mathematical abstractions represent, which helps them to understand the behaviour of a variety of systems. The software provides students with instantaneous feedback which encourages them to explore problems further. Topics covered in the text include signals, systems, convolution, Fourier series and transforms, Laplace transforms, analogue filters, sampling the discrete-time Fourier transform (DTFT), FFT, z-transforms and digital filters. All basic concepts are illustrated by worked examples. End-of-chapter problems include simple drills as well as more challenging exercises that develop or extend the concepts covered. A feature of this text is the software supplied on disk which contains ready-to-run demonstrations, interactive programmes and full-fledged general purpose programmes which runs under MATLAB (both V3.5 and V4.0).
