Signals and Systems

Signals and Systems is a field that studies how information (signals) is transmitted, processed, and understood in various forms, such as audio, video, or data. A signal is any variable that carries information, while a system is a process or device that transforms or interprets that signal. This area of study is crucial in telecommunications, audio engineering, control systems, and more, as it helps us understand how to manipulate signals effectively for clear communication and functionality, ensuring reliable performance in technology we use daily, from smartphones to medical devices.
