This supplement to any standard DSP text is one of the first books to successfully integrate the use of MATLAB® in the study of DSP concepts. In this book, MATLAB® is used as a computing tool to explore traditional DSP topics, and solve problems to gain insight. This greatly expands the range and complexity of problems that students can effectively study in the course. Since DSP applications are primarily algorithms implemented on a DSP processor or software, a fair amount of programming is required. Using interactive software such as MATLAB® makes it possible to place more emphasis on learning new and difficult concepts than on programming algorithms. Interesting practical examples are discussed and useful problems are explored. This updated printing revises the scripts in the book, available functions, and m-files (available for downloading from the Brooks/Cole Bookware Companion Resource Series? Center Web site) to MATLAB® V5 (created with 5.3).

I have been teaching in the areas of politics and literature for a number of years and have been fascinated especially by the work of George Orwell. In the early 1990s I began work on a book on Orwell and thought at the time that my interest in him would be satisfied. However, George Orwell: A Political Life, published by Manchester University Press in 1993, left me feeling that I wanted to say more than the essentially hybrid format of that book had allowed me to say about his political ideas. In 2003, Orwell’s centenary year, I was invited to give a number of papers on aspects of Orwell’s thought and was disingenuous enough to imagine that these could easily be brought together to make a book. Routledge were good enough to express an interest in the project, and so I immediately began to work on my individual papers. But of course I discovered that a great deal more work had to be done on each, and gaps between them, too, had to be filled. I am very grateful to those at Routledge who expressed an interestin the original project and to those, especially Harriet Brinton, who bore with me when it became clear that the task would be more difficult than originally envisaged. I would also like to express my gratitude to two friends, Claire Lightowler and Stanley Kleinberg, who read most of the original draft – in fact, in Stanley’s case, all the original draft. Their comments were very helpful and caused me frequently to rethink my approach. I am not a good proofreader; in fact, if I were any younger I would have been classified as dyslexic. In those days, however, that option was not available – only indolence. It has been my great good fortune to have a friend who is a meticulous proofreader and I am most grateful for the help that John Stewart offered and gave. Finally, my wife has been enormously and unstintingly supportive of my work. This project would not have been possible to complete without her help. All of these people are partly responsible for the successful completion of what follows, but only I am responsible for its deficiencies.
