Inherent noise sources (thermal noise, shot noise, flicker noise, burst noise, intermodulation noise). Calculation, measurement and minimization of inherent noise. Overview of modern passive and active discrete components. Low noise precision amplifiers, high resolution A/D converters. Characteristics that affect the accuracy of A/D converters - interference noise sources (crosstalk, coupling, jitter). Methods for reduction of interference noise - optimal design of the schematic, pcb design, cabling and shielding. Design a mixed (analog and digital) electronic system, layout design. Power electronics circuit: problems in designing high-voltage switching circuits. Switching power supply - minimization of interference, efficiency. Design of digital electronic circuits. Design of electronic circuits at high frequencies (impedance of lines, transmission lines, termination of lines ...). Design of low power system
