# General Exams

For both areas of concentration in Electrical Engineering, Master’s comprehensive and Doctoral general exams (written part) are each given twice yearly, generally in January and May. **Except for where noted below under a track**, the exams are to be of the open-book/open-notes variety, and one hour per question is allotted. An oral exam is mandatory for Ph.D. students, and usually takes place shortly after the written exam; for Master’s students an oral exam may follow the written exam at the discretion of the student’s advisory committee. The written exams are structured as follows:

**Information, Communication, Decision, and Biosystems Track (Dr. Shalabh Gupta)**

The Master’s exam consists of a question in each of the required core courses [ECE 5101, ECE 6111, ECE 6122, ECE 6151, ECE 6439]. Questions from each of these areas, plus from two other areas, as designated by the student’s committee, comprise the Ph.D. exam, which takes place on two successive days. The exam structure is summarized below.

*Day 1*

1. ECE 5101: Introduction to Systems Theory

2. ECE 6111: Applied Probability and Stochastic Processes

3. ECE 6122: Digital Signal Processing

4. ECE 6439: Estimation and Filtering Theory

5a. ECE 6151: Communication Theory (M.S students only)

*Day 2 (Ph.D. only)*

5b. ECE 6151: Communication Theory (Ph.D. students only)

6-7. Two questions on any two advanced courses chosen by the student in the student’s area of specialization within the Information, Communication, Decision, and Biosystems program [e.g., ECE 6123, ECE 6435, ECE 6126].

In the interest of uniformity and of fairness in grading, questions written by Information, Communication, Decision, and Biosystems Group faculty members for students in other areas will follow the same procedures as above; that is, these students will answer their questions alongside those Systems students taking the same exam. In practice, students from other areas will generally have only one or two Systems questions, and hence they shall be allotted a one or two hour period for their answers.

**Electronics/Photonics/Biophotonics Track (Dr. Helena Silva)**

*Approved by the Electronics/Photonics/Biophotonics division in Spring 2014*

- The general exams will be given twice per year (January and May), in general, during the
**same week as the Systems general exams**. - Written Exams will be required on
**6 courses (PhD) or 3 courses (MS-Plan B)**from the courses/areas listed below. General Exams may not be taken on independent study courses. - Exams will be
**closed books**/ closed notes / no computers, phones, etc. - There will be an
**oral**component of the general exam (typically as part of the prospectus defense). - An
**average**score of at least**70%**will be required for passing the written exams taken by a student (exact passing score is instructor’s decision depending upon exam difficulty). - Ph.D. Students will be required to finish their exams in their first
**4 -6****semesters**. - Students will have
**only 2 attempts**to pass their exams. The student needs to**repeat**only the failed exams. - Students will have to take the exams either all at the same time or in
**blocks of three courses at a time**.
