## Fundamentals of Signals and Systems: Using the Web and MATLABFor a Signals and Systems course in Engineering departments. Developed from Professor Kamen's best-selling text Introduction to Signals and Systems, this forward-looking text presents an accessible yet comprehensive analytical treatment of signals and systems and also incorporates a strong emphasis on solving problems and exploring concepts using MATLAB. A MATLAB tutorial is provided on a disk which is available for student/instructor use, and all examples in the text are developed in terms of the Student Edition of MATLAB '. |
