This course introduces basic concepts in the modeling and analysis of engineering systems and fundamental topics in communications, control, and signal processing. Includes classification of systems; signals & systems characterization in time and frequency domains, Fourier and Laplace transforms; introduction to discrete-time systems and digital signal processing. The successful student will be able to understand and compute input-output relationships for linear systems, in both the time and frequency domains. The student should gain intuitive understanding of time-domain vs. frequency-domain behaviors and should be able to analyze and design simple systems. Both continuous- and discrete-time systems will be covered, but with slightly more emphasis on continuous-time systems as discrete-time systems are covered in more depth in Digital Signal Processing (ECE 4213).
