This is a progressive assessment consisting of the following:
Assessment task 1 (Practical Exercises): 30%
Practical Laboratories: The students will have to complete minimum of three laboratories as specified by the teacher for the practical exercises and demonstrate the understanding of amplifier fundamentals through the developed project.
Project Modules: The students will design and develop the project modules (minimum two project modules) as specified by the teacher for the practical exercises and demonstrate the understanding of amplifier fundamentals through the developed project.

Assessment task 2 (Written Assessment)
Written Reports for the Laboratories and Project Modules :10%
Written technical report as per the requirement and specifications for each of the project modules should be submitted by each student individually.

Written Assessment : 60%
The students will have written exam to demonstrate their theoretical knowledge based on basic amplifier circuits as detailed in the course.

This course is graded using the following course grades-

CHD- Competent with High Distinction
CDI- Competent with Distinction
CC- Competent with Credit
CAG- Competency Achieved - Graded
NYC- Not Yet Competent
DNS- Did Not Submit for Assessment. (This grade is only to be used where the student’s attendance in the course has been ‘confirmed’ (but they have not participated in any form of assessment and did not withdraw by the census date.)
