Planned learning activities and teaching methods
Techning methods include lectures and practical laboratories. Course is taking advantage of e-learning (Moodle) system.
Assesment methods and criteria linked to learning outcomes
In exercises, students can obtain up to 20 points. The examination proper is a written examination and students can gain for it up to 80 points. The examination focuses on the ability to orient oneself in the design of simple circuits for A/D and D/A converters and the ability to analyse complex integrated structures of A/D and D/A converters.
Language of instruction
1. Circuits for precise pre-processing of signals:
1.1 Amplifiers with electronic switched gain, precise analog multiplexers or demultiplexers, filters for A/D and D/A converters
1.2 S/H and T/H circuits: parameters and circuit solutions
2. D/A converters:
2.1 Parameters of D/A converters
2.2 Circuit solutions of D/A converters
3. A/D converters:
3.1 Parameters of A/D converters
3.2 Circuit solutions of A/D converters
4. U/F converters
D/A and D/A converters, the properties of integrated converters and their possible applications. They should be able to orient themselves in signal pre-processing circuits such as precise switched amplifiers, anti-aliasing filters, and sampling circuits with memory.
Specification of controlled education, way of implementation and compensation for absences
Computer exercises are obligatory. Justified absence from computer exercises can be made up after prior arrangement with the instructor, usually in the credit week.
