Subject Information and Policies


Fundamentals of signal and system analysis, focusing on representations of discrete-time and continuous-time signals (singularity functions, complex exponentials and geometrics, Fourier representations, Laplace and Z transforms, sampling) and representations of linear, time-invariant systems (difference and differential equations, block diagrams, system functions, poles and zeros, convolution, impulse and step responses, frequency responses). Applications are drawn broadly from engineering and physics, including feedback and control, communications, and signal processing.

6.003 Grade

Your grade in 6.003 will be the weighted average of the following component grades:
10%   Midterm 1
15%   Midterm 2
20%   Midterm 3
40%   Final Exam
15%   Homework, Participation, Other Factors

Due Dates, Lateness Penalties, and Extension Policy

Homework and Engineering Design Problems must be completed by the scheduled due dates unless officially excused by an Instructor, a Dean, or a Medical Official. Each student will be allowed to turn in one late homework assignment without penalty. The grades on all other late assignments will be multiplied by 0.5 (unless officially excused by an Instructor, a Dean, or a Medical Official).

Midterm Exams

Three midterm examinations will be held, each on a Wednesday evening from 7:30-9:30pm, on October 5, October 26, and November 16. Requests for a conflict exam must be submitted no later than 1 week before the scheduled exam. Requests made after this cutoff date will be denied.

Final Exam

A three-hour final exam will be given during the Final Examination Period at the end of the semester. The final exam will be comprehensive across all materials in this subject, however, materials since the midterms may be weighted more heavily. The final exam will be scheduled by MIT's Registrar's Office. Conflicts with the scheduled time must be resolved by scheduling a conflict examination with MIT's Registrar's Office.

Regrade Policy

If you find a grading error in an examination or homework assignment, please submit your exam/homework along with a cover sheet that describes the error that you found to your TA. We will review your concern and then regrade the entire exam/homework to try to eliminate the error that you identified as well as any other grading errors. Requests for regrades must be made within one week of the date when the graded exam/homework was returned.

Collaboration Policy

We encourage students to discuss assignments in this subject with other students and with the teaching staff to better understand the concepts. However, when you submit an assignment under your name, we assume that you are certifying that the details are entirely your own work and that you played at least a substantial role in the conception stage.

You should not use results from other students (from this year or from previous years) in preparing your solutions. You should not take credit for computer code or graphics that were generated by other students. Students should never share their solutions with other students.

Any student caught plagiarizing will receive a grade of zero on the assignment. All incidents of plagiarism will be reported to the Committee on Discipline (COD). More information about what constitutes plagiarism can be found at
