ELECTRONIC DEVICES AND CIRCUITS

OBJECTIVES of the subject:

• Lectures presents:
  
  • the principles of circuit analysis and design,
    
  • the basic concepts and characteristics of the electronic devices and circuits.
    
• Tutorials complete the lectures and develop the ability of analyzing actual electronic circuits that implements the basic circuits presented at the lectures.
  
• Laboratory work has been developed to give the student practice in the experimental setup, measurement, and analysis of basic electronic devices and circuits.
  
• The course as a whole outlines some ways of thinking about analog circuits that hopefully will help to develop intuition. By the end of this subject, students should have acquired reasonable proficiency in the analysis and design of basic electronic circuits.

Notes:

1. A successful final qualification is conditioned by obtaining at least the mark of 5 at examination and laboratory.
   
2. Students must be fully aware, however, that any sort of cheating will have severe consequences, and that cheating includes things such as unauthorized notes stored in calculators or any sort of communication with other students during exams.
