Course detail

# Analog Electronics 1

FEKT-BPC-AE1Acad. year: 2020/2021

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 and stabilizers, signal converters 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.

Prerequisites

Knowledge on the level of electrotechnical courses of the 1st year of study is required. A student should be able to:
- discuss basic principles and theorems valid for electrical circuits,
- solve linear and simple nonlinear resistive circuits,
- solve linear circuits in a harmonic steady state,
- discuss properties of passive linear circuits of the 1st and 2nd order – RC and RL networks, RLC resonant circuits,
- express transfer and immittance functions in complex and operational forms,
- specify types of semiconductor diodes and transistors and discuss their functioning,
- choose and use proper measuring instruments to measure parameters of an electronic circuit,
- use basic regimes of the PSpice simulator,
- form a simple program (function) in the Matlab language.
Work in the laboratory is conditioned by a valid qualification of a "trained worker" according to Notice 50/1978 Coll., which students must obtain before the start of teaching. Information on this qualification is given in the Dean's Directive Familiarization of students with safety regulations.
