Anotace:

Methods of measurement of electrical quantities (voltage, current, power, frequency, resistance, capacitance and inductance), measuring transducers, A/D and D/A converters, electrical and electronic measuring instruments are introduced. Test and measurement methods in digital technology using analog and digital oscilloscopes and logic analyzers are presented. Finally the transmission of digital signals over the transmission line is introduced and reflectometry (TDR) principle is presented.
