Synopsis:

The subject provides students with basic knowledge of digital technology. It deals with the digital systems, binary codes, expression and simplification of logical functions with regard to the synthesis of combination logic circuits. Attention is also given to sequence circuits, including examples of their synthesis. Special attention is devoted to funtiona and design of memory elements - S-R, J-K, T, D. Attention is also given to methods of digital circuits diagnostics.

Study Objective:

The aim of the course is to familirize students with the principles of both classical and programmable logic devices and their practical use in the design of digital systems.

Teaching digital circuits will be based on the classical description of logic gate use and a description of the VHDL language. In the context of the seminars, students will work with real logic gates, measure their static and dynamic properties. They will verify the function of digital circuits in the simulator and will implement them in the programmable gate array. The seminar will conclude with a project, in which students will explore the design and testing of a simple digital system using the programmable gate array.

Study materials:

Recommended literature will be specified by lecturer.
