# Analog Electronic Circuits

FEKT-BAEOAcad. year: 2017/2018

Contents of the course are theoretical basics and principles of analog electronic circuits, an explanation of functioning of typical connections of particular types of the circuits, including methods of their analysis. Students will become familiar with classification and description of electronic circuits, circuits elements and functional blocks, with fundamentals of real circuits elements modelling, with stability and feedback theories and their practical applications. An emphasis is put on an explanation of the function and the application of basic kinds of the analog circuits, as are circuits with operational amplifiers, electrical filters, basic transistor stages and circuits, amplifiers, rectifiers, stabilizers, signals shapers, analog multipliers, modulators, mixers and oscillators. Students will exercise in the use of Matlab, SNAP and PSpice programs at the computer-aided analysis of analog circuits, and deepen practical skills at measuring their properties.
