SIGNALS AND SYSTEMS

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.
