The various components of the course encourage students to think graphically and to draw, before they reach for mathematical formulae. Lectures, discussion sections, and instructors office hours promote group work by engaging the students in a collaborative learning environment where they divide into groups of 3-5 students and discuss the solutions to various problems. In discussion sections and office hours, students present their solutions to their peers on the board; they generate peer discussion by asking each other questions and assisting each other toward solutions. Recognizing that team work is an integral part of engineering practice, the homework policy encourages collaborative groups of up to five students. Lectures also cultivate group learning. For almost every example problem the students encounter in lecture, they take time to discuss the solution among themselves, explaining concepts and learning about alternative solutions from their peers. Course learning Objectives and Outcomes: This course trains students for an intermediate level of fluency with signals and systems in both continuous time and discrete time, in preparation for more advanced subjects in digital signal processing (including audio, image and video processing communication theory, and. Upon successful completion, a student should: Classify systems based on their properties: in particular, understand and exploit the implications of linearity, time-invariance, causality, memory, and bounded-input, bounded-out (bibo) stability.

Ee 120 continues the tradition of its lower-division prerequisite course ee 20N by requiring students to apply a fundamental knowledge of mathematics, science and engineering to not only solve electrical and computer engineering problems, but also to recognize the multidisciplinary reach of the topics and. Students learn modern skills, techniques and engineering tools. They refine their skills in back-of-the-envelope and design-oriented analysis. They learn to model signals and systems, with an eye toward design. Problem sets and exams are designed to probe a thorough understanding of fundamental concepts and to de-emphasize rote algebraic manipulation. Exam problems insist on refined and to-the-point responses; limited space is allocated for each problem to encourage students to think more clearly and logically, and to articulate their responses efficiently and without clutter.
