After successfully studying course of Electronics students will be able to:

1. Understand the basic electrical engineering principles and abstractions on which the design of electronic systems is based. These include lumped circuit models, digital circuits, and operational amplifiers;

2. Understand the physical bases of solid state electronics;

3. Build circuits and take measurements of circuit variables using tools such as oscilloscopes, multimeters, and signal generators. Compare the measurements with the behavior predicted by mathematic models and explain the discrepancies;

4. Analyze problems in the field of basic electronics and find their solutions, analyze and formulate conclusions;

5. Use literature and Internet resources to understanding and solving the problems of electronics;

6. Use teamwork skills laboratory, assuming the role of the leader or the coordinator of the experiment;

7. Organize a work and take responsibility for results of his work;

8. Appreciate the practical significance of the systems developed in the course.

To gets assessment of laboratory necessary is to execute all of labs, to prepare reports and oral presentation of results. The absence of 50% of the laboratory makes it impossible to obtain credit from the laboratory.

The assessment of labs is necessary condition to oral assessment of lecture.

Evaluation of student work:

• assessment of labs ;

• oral assessment of lecture.
