Circuits and Systems Track Update
Electrical and Computer Engineering
Tufts University
Summary:
The electrical and computer engineering department has deliberated for over a year, and
has voted unanimously to update the circuits and systems track. This specifically
concerns the following existing course sequence for the two majors:
Electrical Engineering Majors
Computer Engineering Majors
In this sequence ES-3 and EE-26 are only shown to highlight the pre- and post- courses
in the sequence. These courses will remain unchanged. Note that in the current system,
EE-13 comes before EE-11 and EE-12 in this sequence.
The main changes are as follows:
(1) Consolidate EE-13 and EE-11 into a single course, with the number EE-21 offered in
spring semester. The new name for the course is Electronics I
(2) Rename EE-103 as EE-23 to be offered in fall semester.
(3) EE-12 will now be offered in the fall semester renamed as EE-22: Electronics II.
(4) Add a new course EE-31: Junior Design to be offered in Spring semester of the junior
year. This course adds a much needed “project based learning” component in the EE
curriculum.
The new sequence is as follows:
Rationale:
It was realized that the syllabus for EE-13 and EE-11 had much overlap with preceding
course (ES-3) and among themselves. For example, circuit theory treatment was
repeated in EE-13 (from ES-3). Signal flow graphs analysis was also covered repeatedly
in EE-13, EE-11 and EE-12.
Also discussion on s-transform, z-transform and Fourier transform was not coherently
planned among these courses. EE-13 discussed s-transforms, which were covered
again in EE-102. Moreover, it was also realized that EE-102 was specifically a
transforms and linear systems course for undergraduates. It does not qualify as a 100
level course.
Department strongly supports the idea of project-based learning. It believes that such a
component could be incorporated into the curriculum in the junior year by the
introduction of a new course EE-31: Junior Design. This course provides means to apply
concepts from analog circuits, digital circuits, linear systems and microprocessor-based
systems learnt in earlier classes for hands-on problem-solving of real-life engineering
problems. This project component is similar to the senior design project, except that it is
more structured and organized.
To achieve these objectives, he department agreed to restructure the syllabus and
change the names and descriptions for these courses to stay relevant and provide a
more focused and learning sequence to our students.
The main consequence of this change is an overall reduction of one required course for
both electrical and computer engineering majors. Also, the movement of the courses
from spring to the fall semester for EE-12 and EE-13 provide a more equitable
distribution of workload for the students.
Detailed Changes in each of the courses:
1) The new EE-21: This is a combined EE-13 and EE-11 course that will be offered in
place of EE-13. Some topics from EE-13 such as frequency response and active filters
will be moved to EE-21. Signal flow graphs discussion from the old EE-13 is dropped.
Course starts with FET transistor discussion and not BJT, due to the prevalence of MOS
circuits in today’s world. Also computer engineers get to see MOSFETS in their
curriculum, which is not currently possible. Laplace based frequency response
discussion is replaced by phasor based understanding. Laplace transforms will be
discussed next semester in detail in the new EE-23 (that was EE-102).
2) The new EE-22: Course will start where EE-21 left off. BJT device and circuit
operation would be introduced for the first time. Integrated circuit realizations using
active loads will be the main focus. Differential and multi-stage amplifiers will be covered
in much more detail. Some control theoretic concepts based on the linear systems
understanding of analog circuits will be proposed. Advanced circuits will be covered.
3) The new EE-23: This is the renaming of the EE-102 course with slight changes in the
curriculum. Bilateral and unilateral s-transforms and z-transforms will now be covered.
Some control theoretic concepts will be covered in parallel with EE-22.
4) The new EE-31: This is the newly proposed “junior design” course to be offered in the
spring semester of the junior year. The course facilitates project based learning earlier
into the sequence. Application of principles of analog and digital circuit design,
microprocessor and computer architecture, signals and systems theory to a well-defined
problem from concept to prototype will be implemented.
Timeline:
Since the courses suggested here are for sophomore spring semester onwards, we
expect the freshman class (class of ’14) will be able to follow the new sequence
beginning Spring 2012. The class of ’13 will not be affected, since we plan to offer EE-11
and EE-12 as well to make sure they finish their promised sequence. To be more
precise, EE-11 will be offered in fall 2011 and EE-21 will be offered in Spring 2012, and
then EE-11 will be discontinued with EE-21 offered each spring. Similarly, EE-12 will be
offered on Spring 2012 and EE-22 will be offered in Fall 2012, and then EE-12 will be
discontinued, with EE-22 repeated each fall semester. The new course EE-31: Junior
design will start Spring of 2013. EE-102 will be offered in Spring of 2012 for the class of
‘13. Note that class of 2012 and class of 2015 will not be caught in the transition period.
