Signals and Systems is a mandatory fundamental course for college students in Electronic and Information Engineering majors. It elucidates the principles and methods in signal analysis and system description and the interaction mechanism between signals and systems. The course is distinct from other courses with its articulate structure, rich contents, and advanced teaching philosophies. During the process of the study, students will be able to understand the core ideas that signal and systems analysis is essentially signal representation and system description, respectively. With different basis functions, signals can be represented in different domains, and thus different approaches can be taken depending on the tasks of signal analysis and processing. Accordingly, systems can be described in different domains, and thus different methods can be taken for system analysis and design.
The future is here: we have entered a new era characterized with informationization and intelligentization, for which Signals and Systems provides the fundamental theories and analytical methods. The course paves the way for the students in relevant majors by establishing the crucial concepts of spectrum and transfer functions, fitting us better in the future.
