Prentice HallCONTACT TIMELectures will be every Tuesday, from 16:30 to 20:30. Learners are expected to attend all lectures.ASSESMENT

Students will be assessed on their laboratory work and laboratory reports, three 90-minute written tests(best two will be taken), and a final written exam of 3 hours.The final mark for this subject consists of an exam mark and a year mark. The exam mark accounts for 60 percent and the year mark makes up the remaining 40 percent.

The year mark is calculated as follows:

SM =0,7(T1 +T2) + 0,3(practical/assignments)

The practical/assignment mark is the average of all the practicals. (Practical assessment is explained in detail in a later section.)In order to gain entrance into the examination for Radio 4, the learner must obtain:

A sub-minimum of 40% for the semester mark.

Must have completed all of the necessary prescribed laboratory experiments to the satisfaction of the lecturer with a laboratory mark of greater than 50%.TEST DATES

The actual test dates will be announced in class.TEST DATES:

RULES

Learners will attend all the lectures and laboratory sessions.

Learners will write all the class tests and hand any assignments on the required dates, learners not handing in assignments (this include lab reports etc.), will be penalized.

Late arrival of learners for lectures or labs will not be tolerated.

Cell phones must be switched off, or switched to silent, during lectures.

Plagiarism will be treated in a very serious light. Tests, Lab reports, etc. must be your own work. If lab reports are copied from fellow learners, all the corresponding lab reports will get a zero mark plus additional steps will be taken.

No credits will be given for previous labs.

If you do not have a laboratory mark exceeding 50%, you will not have exam entrance.SUBJECT OUTCOMES AND SYLLABUS TOPICS

The Department of Electrical and Computer Engineering Technology reserves the right to modify this list of outcomes at any time. Learners will be given timely notice.

SYLLABUS TOPICS
