Textbook: "Signals and Systems"

"Signals and Systems" is a textbook that explores how various types of signals—like sound, images, or sensor data—are processed and analyzed. It explains how these signals are represented mathematically and how systems, such as electronic circuits or software algorithms, manipulate them—for tasks like filtering, decoding, or transforming. The book provides a foundation for understanding how information is transmitted, processed, and interpreted in engineering contexts, essential for designing communication devices, control systems, and digital technology. It bridges theory with practical applications, emphasizing concepts like signal representation, system behavior, and stability.
