Subject aims expressed by acquired skills and competences
To acquaint students with the internal structure of electronic devices, especially with the functions and properties of the analog circuits. Students will be able to recognize common types of electronic components, explain their function and properties. Students will learn to design selected circuits with OZ for evaluation and modification of the analog signal. The students in the course will learn the basics of logical systems, their design, testing and practical application, focusing particularly on programmable logic circuits.
Students will acquire basic knowledge of methods for description, analysis and design of combinational and sequential logic circuits. Emphasis is placed on the ability to create a logical circuit independently based on the verbal assignment of its function. Students will also learn about the principles and the use of A / D and D / A converters and memories that they will be able to include in the logic system. Course objectives Students will be able to interpret and apply basic principles of digital technology used in architectures of programmable logic circuits and at the same time in microprocessor technology.

Summary
The course provides students with the most important functional blocks of electronic devices. These are electrical power supply components and, in particular, analogue circuits for generating, modifying and evaluating the signal. Further, the course introduces students to the basics of digital technology by designing combinational and sequential logic functions. Differences in logic design with conventional integrated circuits and programmable CPLD / FPGAs are explained. In the individual exercises the students verify the function of simple and complex logic circuits in the simulator and also in the FPGA emulator. The topics discussed are the connections between logic circuits and real-world environments, semiconductor memories and digital communications. The course prepares students to work with digital technology and prepares them for other subjects with programmable circuits, embedded systems and microprocessor technology.
