ELG3175: Introduction to Communication Systems (Winter 2018)

(under construction, frequently updated)




Unofficial final exam marks and final grades are now posted. The official grades will be announced by the university in the regular way. If you wish to see your marked final exam paper, it will be available on Thursday May 29, 4-6pm in CBY B508 (TA: Mahdi Khojastehnia, mkhoj015@uottawa.ca). It will not be available at any other time.


Please note the following:


• The final exam has been marked very carefully.

• The marks reflect, as required by the University regulations, the academic performance, not needs/wishes/bargaining abilities etc.

• Everything has already been rounded off to your advantage.

• Marks are non-negotiable and non-discussable.

• If you do believe that a mistake was made when marking, you may request re-marking, but only once.

• All requests for re-marking have to be done in writing using the official remarking form provided by the TA. Read carefully the rules of re-marking on that form. The revised mark is considered to be final and no further requests for re-marking will be accepted.

• The marking margin (2.5 points) has been added to the final mark to compensate for inaccuracies in the marking. If you do request re-marking, the margin becomes null as I’ll double-check everything to eliminate any inaccuracy.

• These rules are absolutely FIRM and NON-NEGOTIABLE.

*Please give detailed solutions, not just final answers. Explain all important steps, do not skip them!

*Plagiarism (i.e. “cut-and-paste” from a student to a student, other forms of “borrowing” the material for the assignment) is absolutely unacceptable and will be penalized. Each student is expected to submit his own solutions. If two (or more) identical or almost identical sets of solutions are found, each student involved receives 0 (zero) for that particular assignment. If this happens twice, the students involved receive 0 (zero) for the entire assignment component of the course in the marking scheme and the case will be send to the Dean’s office for further investigation.
