Recommended reading

You will be issued with a reading list and exercises to work through before your first residential week via the Virtual Learning Environment (VLE) to help prepare you for the MSc course.

This online material will cover:

  1. Charge conservation, Kirchhoff’s laws, mesh/nodal analysis;
  2. Concepts of ideal voltage and current sources, and impedances;
  3. Thévenin and Norton theorems with emphasis on the concepts of input and output impedances;
  4. Frequency response of a.c. networks including Bode diagrams, second-order and resonant circuits, damping and Q factors;
  5. Laplace transform methods for transient circuit analysis with zero initial conditions. Impulse and step responses of second-order networks and resonant circuits;
  6. Probability theory and stochastic processes.

You must work through this material before the course begins in earnest. If you have a Physics background you may find parts of the content familiar, but there will be new contexts and content. If you have a background in Mathematics you may find most of this material new. 

 

Accommodation

Accommodation is not included in the course fee but may be available at your college and at Rewley House.

Bed and breakfast accommodation at other University colleges can also be booked on the Oxford Rooms website.

 

Libraries

Radcliffe Science library

The Radcliffe Science Library (RSL) www.bodleian.ox.ac.uk/science is the main science research library at the university. The library holds copies of all of your reading list items, and most of your engineering library research will be done using this library’s resources. The library is located less than 5 minutes away from the Engineering Science department, at the corner of Parks Road and South Parks Road.

The subject librarian responsible for Engineering Science is Alessandra Vetrugno (alessandra.vetrugno@bodleian.ox.ac.uk), based at the RSL.

 

The Department for Continuing Education

The Department for Continuing Education is based at Rewley House in Wellington Square, only five minutes walk from the Department of Engineering Science (Thom Building).

In addition to supporting the various aspects of the course that involve online learning, the Department has facilities available to students during their attendance in Oxford. In particular, the Department has a Graduate Room - a study space dedicated to graduate students with lockers, printing facilities and refreshments. The Graduate Room is accessible from 8.00am to 10.00pm (24hrs for students using the Department’s overnight accommodation). The Continuing Education Library, also located at Rewley House, has quiet study space and a ‘Reading Room’.

 

IT requirements

In order to participate in the pre-course material you will need access to the internet and a computer meeting our recommended minimum computer specification, which can be found online at onlinesupport.conted.ox.ac.uk/TechnicalSupport/YourComputer.php

 

Fees

This unit can only be taken as part of the MSc in Microelectronics, Optoelectronics and Communications.

Teaching methods

Each of the six taught units will typically follow the structure below:

  1. Online material and exercises using the Virtual Learning Environment (VLE). We would expect you to take 12 weeks to work through this material.  We will expect you to read specific material online and be familiar with the necessary pre-requisites of the course before each residential week in Oxford.
     
  2. A residential week in Oxford during which you will attend classes, complete tutorial exercises, participate in tutorial classes, meet your personal tutor and, where necessary, complete practical assignments.
     
  3. Assignments which are available online and which must be completed and submitted by the deadlines (see Key Dates).

This course is taught by members of the Engineering Science Faculty, who you will as lecturers, as tutors for classes, or as your dissertation supervisor. One member of faculty will be assigned to you as a ‘personal tutor’ at the start of the course. He or she will provide advice and guidance, and discuss your academic progress. Your personal tutor will meet with you at each of the residential weeks, and you can contact him or her by email.

Your course supervisor will write a formal report on your progress three times a year on the online Graduate Supervision System (http://www.admin.ox.ac.uk/gss/). You will be able to view that report and will be asked to reflect on your progress as well. 

Virtual Learning Environment

This course uses a Virtual Learning Environment (VLE), which is a web-based application using WebLearn.

Access to the course VLE is via an internet browser using your University Single Sign-On account. When the course has started and you have activated your Single Sign-On under “My Active Sites” you will have access to the student forum, information about student support, course documents and examiner reports.  If you are unable to access WebLearn, please email the Registry with details of your Single Sign-On (moac@eng.ox.ac.uk).

You will be given access to an 'Induction' VLE which houses supporting materials for the MSc on Microelectronics, Optoelectronics and Communication at the start of the academic year, and to separate sites for each unit as and when you are due to take them.

During the course you will also be required to submit work through our online Moodle Assignment Submission System. A link to the online Submission System can be found here.

 

Assessment methods

There will be two problem sheets - neither of which are formally assessed - that will be provided during the residential week. These first two assignments will not contribute to your overall degree outcome. You will receive verbal feedback from the tutor on your work for both problem sheets at the tutorial classes during the residential week and written feedback via the VLE.  At the end of the residential week, two further example sheets will be made available that will accompany the material to be covered via the VLE. Again, they will not contribute to your overall degree outcome, and written feedback will be provided.

Finally, there will be two examinable papers that will be provided towards the end of the 12 week course. These papers will be formally assessed with the outcome providing the mark for the completed unit. They will be distributed online and must be submitted for assessment online. You must gain a pass in both of these examinable assignments in order to pass the whole unit.

If you fail one of the assignments but pass the other, the mark from the assignment that you passed will be carried forward (further information can be found in the Exam regulations and conventions). For the assignment you failed, you will be set a new assignment and must re-submit this. Additional worked examples and problems may also be provided via the VLE. 

Application

This unit can only be taken as part of the MSc in Microelectronics, Optoelectronics and Communications.
