2. Interconnections between systems (circuits). General view on source and consumer (input impedance, open circuit voltage, inner impedance of the source,...). Impedance matching.
3. Circuit characteristics in the time and frequency domains. Transient effects in the DC circuit. Frequency characteristics of the reactance circuit.
4. Electric current in semiconductors. Types of conductivity, semiconductor junction - its behavior with forward and backward polarization. Bipolar transistor - the transistor effect. Elementary transistor circuits.
5. Unipolar transistor MOS. Elementary circuits. Complementary transistors and their use - CMOS structures.
