Course Description

The “Signals and Systems” course in electrical engineering covers fundamental principles related to signals and their behavior in various systems. Students learn about signal representation, including discrete-time and continuous-time signals, as well as Laplace and Z transforms. The course also emphasizes linear, time-invariant systems, such as difference and differential equations, block diagrams, and frequency responses. Real-world applications in fields like communications, control systems, and signal processing are explored, making this course essential for understanding and designing efficient engineering systems.
