### Course content

The course gives an introduction to electrical concepts and analog circuit theory as a base for understanding both electrical and computer engineering. It also provides a foundation for understanding and designing simple circuits and systems built with digital electronic circuit elements.

Examples and exercises provide skills learning for using basic laboratory equipment and training laboratory work and report writing.

Themes are: Conventions, circuit elements, Ohm´s law, Kirchhoff´s laws, simple resistive circuits, techniques of circuit analysis, capacitance, inductance, and first order RC-circuits (natural and step response). Simplified properties, function and use of diodes and MOSFET transistors. Number systems, binary arithmetic. Boolean algebra, logic gates, simplification methods, combinational logic and simple memory components, flip flops, counters, shiftregisters, and simple arithmetic circuits. Time delay, performance, area, and power consumption for simple digital circuits.
