Anotation:

The course is dedicated to methods for preprocessing, digitalization and reconstruction of continuis signals. It is focused to the methods for achieving of high precision of transmission and suppression of spurious components. The laboratory exercises are divided into two parts: the first part is classical tasks; the second one is individual project of design of typically data acqusition system. The teaching is supported by the CAD system for measuring circuits.

Course outlines:

1. Operational amplifiers for signal conditioning, negative feedback
2. Voltage, current, integration, charge, differential, instrumentation, insulation amplifiers
3. Signal processing for resistive, capacitance and inductance sensors, coherent detection
4. Signal processing for RTD, thermocouple and semiconductor temperature sensors
5. Methods of nonlinear signal processing, signal compression and expansion
6. Nonharmonic signal processing, rectifiers, RMS and peak to peak converters
7. Signal filtering, analog and switching filters design and application
8. Analog signals multiplexing and sampling, voltage references
9. High speed signal digitization, sampling, quantization, flash, half-flash and approximation A/D converters
10. High resolution signal digitization, integration and delta sigma A/D converters, dithering
11. Signal reconstruction, direct digital synthesis
12. Spectral analysis periodic and non-periodic signals, windowing
13. Testing of digitizers, sine wave fit test, spectral frequency test, histogram test
14. Hardware design techniques of A/D systems, grounding, shielding, noise reduction
