7. 6 Course Syllabus Course Aim: To introduce class participants to the basic concepts of signal and systems analysis as a fundamental analysis and design tool in electrical and computer engineering. To develop an understanding the fundamental concepts and applications of continuous and discrete time systems. Analyze the behavior of each type using appropriate methods. To develop an understanding of the time-domain and frequency- domain viewpoint and role of transforms. To develop skills in the mechanics of Fourier, Laplace and Z- transforms, and the use of DFT. To give students knowledge and ability of determining the stability of a system for both continuous and digital systems. To provide the students an opportunity to apply the knowledge of above material in a practical (project) experience
