ECE 202 Signals and Systems

Catalog Description

ECE 202 SIGNALS AND SYSTEMS Mathematical framework associated with the analysis of linear systems including signal representation by orthogonal functions, convolution, Fourier and Laplace analysis, and frequency response of circuits and systems.

Textbooks

Objective

The goal of this course is to expand your problem solving range to include generalized systems. You will acquire additional knowledge relating to system analysis in the frequency and complex frequency domain, using both the Laplace and the Fourier transforms. By the end of the course, you will be able to design and analyze frequency selective filters.

Grading

There will be three exams including the final. All exams are equally weighted. There will be regular homework assignments. The exams contribute 60% and assignments contribute 40% to the final score.

Topics

• Overview of Signals and Systems (Ch. 1)
• Mathematical Description of Signals (Ch. 2)
• Review of complex numbers (Appendix H)
• Convolution (Section 3.6)
• Singularity Functions (Sections 2.3 and 2.9)
• Description and Analysis of Systems (Ch. 3)
• Review of RC and LR circuits (ECE 201 and Section 6.4)
• Fourier Series (Ch. 4)
• Fourier Transform (Ch. 5)
• Review of RLC circuits (ECE 201 and Ch. 6)
• Sampling and the Discrete Fourier Transform (Ch. 7)
• System representation: differential equations and state-space analysis (ECE 201 and Section 12.13)
• Laplace Transform (Ch. 9)
• Laplace Transform Analysis of Signals and Systems (Ch. 10)
• Resonance phenomena, Filter Design (Ch. 10)
• Correlation, Spectral Energy/Power Density (Ch. 8)

Miscellaneous

Homework will be assigned regularly. Generally you get full credit by attempting all the problems, with points subtracted to draw your attention to errors the grader reqards as important or avoidable.

Homework solutions will be provided or discussed in class. It is important, therefore, to submit your assignments before solutions are discussed or made available.

Class attendence is important. Those who do miss class regularly are generally clueless about what is going on in class, and the instructor will show little sympathy on the effects of missing class on your final grade. There may not be a cause-and-effect relationship between class attendence and your final grade, but there definitely seems to be a correlation.

You will use MATLAB extensively to test and better understand theoretical concepts from the course. Additionally, Multisim will be used in some homework assignments as well.
