 Synopsis:

The course is designed to acquaint students with the basics of analog electronic circuits. The first part is devoted to fundamental transistor amplifiers and elemental structures of analog integrated circuits. Then the typical applications of operational amplifiers are introduced, including nonlinear networks and basic frequency filter design and implementation. Problems of oscillators are discussed at the conclusion.

 Study Objective:

The course is designed to acquaint students with the basics of analog electronic circuits.
The course is completed by final examination during exam period. This consists of a mandatory written test and an optional part (an exaple calculation and oral part). The optional part of the exam is not required, if a student does not require a better rating than D (satisfactory).
Student can attend the oral exam only if the sum of his points from the semester and mandatory test is greater than 60.
If the oral examination demonstrate a basic ignorance, the student receives F rating, regardless of the gained points.
