Signals And Systems: Continuous And Discrete

The philosophy of the previous edition of Signals and Systems is retained in the fourth edition by continuing to stress the systems approach so that students are provided the tools and techniques for undersanding anu analyzing both continous-time and discrete time linear systems. While the systems approach is applicable to a very broad class of problems, liberal examples based on traditional circuit theory are included in the book to illustrate the various systems analysis techniques that are introduced. The most obvious difference between this edition of Signals and Systems and previous editions is the inclusion of MATLAB for solving many of the in-chapter worked example and the addition of problems and exercises at the end of chapters that require the use of computational aids. The selection of MATLAB as a computer tool was an easy choice for us. Over the past several years MATLAB has become widely used within the engineering curricula and has been integrated into a number of courses. MATLAB provides very powerful computational and graphical capabilities. MATLAB code is very concise and as a result it is possible to express complex ideas using very few lines of code. Another feature of the forth edition is that all of the end-of-chapter. In addition, a number of new problems are contained in the fourth edition.
