This new edition delivers an accessible yet comprehensive analytical introduction to continuous-time and discrete-time signals and systems. It also incorporates a strong emphasis on solving problems and exploring concepts, using demos, downloaded data, and MATLAB?to demonstrate solutions for a wide range of problems in engineering and other fields such as financial data analysis. Its flexible structure adapts easily for courses taught by semester or by quarter. 本書特色　　1 . Extensive use of online demos 　　2 . Use of MATLAB (Version 　　7 . 0) to generate computer implementations of the techniques for signal and system analysis and design 　　3 . Wide range of examples and problems on different areas in engineering 　　4 . Time-domain aspects of signals and systems (Chs. 1 and 2)　　5 . Frequency-domain aspects of signals and systems 　　6 . Fourier analysis of discrete-time signals 　　7 . Fourier theory applied to the study of both continuous-time and discrete-time systems 　　8 . Study of the Laplace transform　　9 . Introduction of the z-transform and the transfer function representation of linear time-invariant discrete-time systems 　　10 . Analysis of linear time-invariant continuous-time systems 　　11 . Transfer function framework 　　12 . Laplace and z-transform frameworks 　　13 . Fundamentals of the state description of linear time-invariant continuous-time and discrete-time systems
