Introduction to mathematical modeling of signals and systems. Designed for the undergraduate course on signals and systems, this text provides a comprehensive overview of fundamental concepts and their practical implications. Since we are dealing with signals, so in our case, our system would be a mathematical model, a piece of codesoftware, or a physical device, or a black box whose input is a signal and it performs some processing on that signal, and the output is a signal. Signals may, for example, convey information about the state or behavior of a physical system.
