2 Why should I take this class? / We study various methods used in analyzing signals and linear systems These methods are fundamental to engineering design and engineering research As most of the systems we study are linear, this course paves the way for numerous fields: Control systems Communications Signal processing Multimedia processing and compression Etc. etc. Even other engineers (chemical, mechanical, bioengineering), but also business people etc. use similar tools! ☺ ☺ ☺ ☺ ☺ ☺ ☺ ☺ ☺
