Learning outcomes of the course unit

On completing the course, students will be able to:
- orient themselves in the selection of circuits for signal preprocessing such as electronic switched circuits, analog multiplexers or demultiplexers,
- be familiar with filtering circuits designed for cooperation with A/D and D/A converters,
- be able to design and apply sampling circuits with memory,
- understand the parameters of A/D converters and be able to design solutions to various types of A/D converters,
- understand the parameters of D/A converters and be able to design them and analyse, and
become familiar with solutions also to other types of converters such as U/F or D/F converters.

Prerequisites

The basic knowledge of analog and digital circuits is required.

Co-requisites

Not applicable.

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.
