Overview

In this Signals and Systems sequence, students learn theoretical and applied methods of signal representation and processing, communications, and design of linear systems. Matlab is used extensively throughout the sequence as a tool for exploration, visualization, and design.

ECE 315 introduces students to the fundamentals of signals and systems including representation of continuous signals, basic system properties, linear time-invariant systems, Fourier series, Fourier transforms, and filters.

ECE 316 continues the sequence with treatment of concepts in sampling, modulation, multiplexing, the Laplace transform, and the z-transform.

Course structure:

• Lectures, 4 hours per week

• Homework, weekly (may be graded or ungraded)

• Weekly quizzes, midterm, and final

• Grading criteria may vary with instructor

Required TA Skills

1. You need a solid background in the material covered in each course:

   • For ECE 315 - convolution, linear time-invariant systems, impulse response and transfer functions, Fourier series, Fourier transforms (single and multi-dimensional), FFT, IIR and FIR filters

   • For ECE 316 - sampling and implications in the time and frequency domains, modulation and demodulation, multiplexing, use of the Laplace transform in design and analysis of continuous-time LTI systems, use of the z-transform in design and analysis of discrete-time LTI systems

2. TAs must have a solid background in linear algebra and calculus (differential and integral)

3. TAs must be experienced users of Matlab and Matlab Simulink

TA Responsibilities

Teaching assistants are required to:

1. Grade homework sets in a timely manner and upload student scores and feedback to D2L.

2. Hold office hours for 2 hours per week; be responsive to student email questions.

3. There may be other responsibilities depending on the instructor such as hold exam review sessions, proctor or grade exams, or other assistance to instructor if requested.

4. Be in contact with the instructor and keep them informed of any problems they observe in homework or office hours.
