内容説明
Exhaustive, definitive and comprehensive, this under-graduate introduction to modern methods of Digital Signal Processing (DSP) encapsulates curricula for degree courses in electrical & control engineering, communication systems engineering, applied mathematics and computer science. It emphasises current programming practices and applications of DSP, with focus on designing algorithms and DSP in communications and control. It introduces underlying principles and mathematical models for analysing and processing different types of digital signals. Readers will also gain an understanding of software engineering methodologies used in designing and constructing DSP packages. Case studies in the book are on modelling theory, propagation and scattering of waves, novel cryptography methods, and digital watermarking for IT security.
