Course Website

This course has a website: You will need to check it periodically throughout the semester for information concerning reading assignments, homework assignments, exam information, and projects.

Course Description

This is an introductory course to signals and systems with specific attention to techniques for their modeling and analysis. Continuous-time signals and systems, discrete-time signals and systems, linear time-invariant systems, convolution integrals and sums, Fourier Series, Fourier, Laplace and Z-transforms, and system functions will be studied.

Course Lecture and Recitation Organization & Attendance

This course covers an incredible amount of material. The most important thing you should do to excel in it is to attend the lectures and take notes, as the lectures will best indicate the selection of the most important concepts and topics. The course has a significant computational/calculus component, and these aspects will be emphasized and practiced during recitation. For this reason, attendance in the recitation is mandatory.

Grading Policy

There will be graded homework assignments, recitation quizzes, a midterm and a cumulative final exam. These will count towards the final grade as follows: homework (15%), recitation quizzes (20%), midterm exam (30%), final exam (35%). Because we will go over solutions in recitation, late homework can not be accepted. If you wish to dispute the grading of a homework/project/exam, you must attach to the homework/project/exam a piece of paper outlining your complaint and return it to the instructor within 2 business days after the homework/project/exam is returned. Any disputation of grading which does not follow these guidelines will not be accepted, and may lead to a reduction in your grade.
