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.

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

1. Introduction, safety, organization. Input circuits of measuring devices -
dynamic parameters
2. Input circuits of measuring devices - disturbance immunity
3. Generators of testing signal. Direct digital synthesis
4. Measuring voltage and current amplifiers
5. Mean value and RMS converters, non-linear amplifiers
6. Analogue time-continuous filters, switched capacitor based filters
7. Oscillators and mixers

comparison with professional solution
9. Project: block design
10. Project: model part I
11. Project: model part II
