General: The class

1) introduces students to the basic types of signals and systems encountered in engineering and to important properties of these systems;

2) introduces students to methods of characterizing and analyzing continuous-time signals and systems in the time and frequency domains.

Covered topics: signals and systems, systems properties, linear time-invariant (LTI) systems, convolution, differential equations, singularity functions, eigenfunctions, Laplace transform, Fourier series, Fourier transform, frequency analysis of LTI systems, filters.

The workload for this course consists of the following: two class meetings and two laboratory sessions per week. Class time is divided between short lecture segments on key concepts and in-class group exercises or quizzes. Students are expected to do the assigned reading prior to coming to class so that they are adequately prepared to participate in the interactive problem-solving sessions. The course grade is based on performance on the readiness assessment tests, in-class problems, weekly homework assignments, laboratory projects, a midterm examination, and a comprehensive final examination.

Laboratory

There will be a series of several Matlab assignments to be completed in the laboratory. The laboratory assignments are a required component of the course. Like the homework, Matlab projects must be handed to the teaching assistant in at the beginning of the lab in which they are due.

Homework

There will be regular homework assignments (problem sets). These will be distributed via the course website (http://math.gmu.edu/~igriva/ece220.html). You are expected to do ALL the assigned problems. In making up the exams and in assigning a final grade, I will assume that you have worked ALL the problems. Most exams will include one problem very similar to one of the homework problems. Thus, there will be a very immediate benefit to doing the homework completely and diligently. Each homework will also include the reading to prepare for the following week’s classes. Again, you are required to do this reading before the class meets.Homework must be handed in at the beginning of the class on the day they are due. Late homeworks will not be accepted, as this would prevent prompt posting of the solutions.
