The Reason this Course is in the Program:

The objective of this course is to introduce the students the fundamentals and applications of continuous and discrete-time signals and systems. The time-dynamic equations and solutions of electrical circuits are employed to motivate the basic concepts in signals and systems. The course emphasis is on continuous and discrete-time representation of signals, system modeling and analysis using differential and difference equations, state variables and block diagrams. Mathematical tools of Laplace, Fourier and z transforms are studied in details. The goal is to develop the student ability for solving practical engineering problems, using a system approach, in modern communication and signal processing systems.
