Lab Work on Electronics
The Lab Work on Electronics is aimed at handson acquaintance with the main radioelectronic components. Unlike the other lab works offered by SEG, this Lab Work includes minimum of equipment: an oscilloscope, a tester, and a soldering iron as the main tool. Students do not work with specially designed training models, but with real radio components: resistors, capacitors, diodes, transistors, selfmade coils, etc. The Lab Work begins with an introduction to the main elements  resistance / capacitance / inductance. Afterwards, filters, semiconductors (diodes, transistors), logic operations and TTL logic, timers and transformers are studied. The course ends with assembling a fullyfeatured power supply unit with a stepdown transformer, rectifier, and Lfilter. The total time of the theoretical part is about 30 academic hours, handson activities – more than 50 academic hours.
Before starting the Lab Work, students are required to do the safety (work with a soldering iron, bare lowcurrent live conductors, fluxes and solder) and fire safety training.
