Learning outcomes of the course unit
The student learns to make an analysis and synthesis of various circuits with bipolar and unipolar transistors operating in lineare or switching regime, further linear and nonlinear circuits with operational amplifiers and circuits with comparators. In the laboratory the student learns (next to the mentioned above) also to use the laboratory supply sources, measuring devices, signal generators, oscilloscope nad soldering gun.
Prerequisites
Student must have the previous knowledge from the applied mathematics: – To use and to apply the mathematical operations above complex numbers in the component and polar representation (summation, subtraction, multiplication, division, and rectification of the complex fraction). – To apply the basic principles of the integral and differential calculus of one variable: description of the inductor work, i.e. induction law in the differential and integral form; similarly the dif. and integr. relations between instantaneous values of the current and voltage at the capacitor. Student must have following knowledge and abilities from theoretical electro-engineering: – To be able to practically use and apply the following tools for the analysis and synthesis of electric circuits: 1st and 2nd Kirchhoff´s laws, Ohm´s law, the induction law in the differential and integral form. – To calculate voltage transfer of the divider built from two arbitrary impedances. – To calculate parallel combination of two impedances. – To use the Thevenin theorem in a practical way.
Planned learning activities and teaching methods
Lectures are lead with the massive support of Power-Point. The Power-Point file is available for students. numerical and laboratory excercises are alterned. In laboratories, students measure several exercises (electronic circuits) using oscilloscope. A collection of ca. 50 solved examples is available for students.
