Basic types of circuits and blocks of digital measuring instruments are described and analysed. Range and linearity for analogue circuits and interfaces for digital circuits are analysed in detail. Finally, individual projects including block design, model realisation and parameters verification are solved.

Course outlines:

1. General structure of digital measuring devices and signal generators
2. Directly coupled amplifiers and attenuators, insulating and modulating amplifiers
3. Mean value and RMS converters (knowledge extension to 38EM), peak detectors
4. Analogue time-continuous filters and filters with switched capacitors, oscillators, mixers
5. Reference voltage and current sources, harmonic and function generators
6. Relations between analogue measuring blocks - signal ranges, linearity and noise. Switching and coupling circuits
7. Time and amplitude signal discretisation, samplers, errors
8. Analogue-to-digital converters (knowledge extension to 38EM)
9. Digital-to-analogue converters, signal reconstruction
10. Frequency and phase digital measurement blocks, phase synchronization, direct digital synthesis
11. Interface circuits for standard buses and interfaces
12. Rules for design of analogue and digital parts from the point of view on electromagnetic compatibility
13. CAD of measuring circuits - simulation and its pros and cons
14. Blocks of virtual instrumentation, advantages and disadvantages of virtual instrumentation

Exercises outline:

1. Introduction, safety, organization. Input circuits of measuring devices -
dynamic parameters
