Supervisor:

Department of Biomedical Technology

Synopsis:

The course deals with the following topics: sub-blocks of communication (low-current/powe) and power (high-current/power) electrical engineering, which relate mainly to applications of modern digital and / or analog-digital circuits or digital-analog circuits especially in the field of drive control and actuator), basic concepts and requirements for these circuits, such as their power supply, load capacity, connection to other peripherals, etc., emphasis is also placed on the principles and applications of synchronous and asynchronous communication lines (SPI, I2C, OneWire, USART), programmable circuits (principles of programmable logic, overview of programmable circuits - PAL, GAL, CPLD, FPGA, circuit programming procedures), microcontrollers and microprocessors (8-bit, 16-bit and 32-bit architecture), systems for galvanic isolation of signal and power supply (optocouplers, linear separators, data bus separators), power drivers for motors and other actuators (H-bridges , triac and thyristor control, IGBT transistors).

Requirements:

Credit requirements:

Compulsory attendance at exercises with two permitted absences without the need for compensation. In case of a larger number of absences due to serious reasons, it will be solved individually. Students are required to keep a laboratory diary in which they will record the procedures and measure results during the exercises. This diary is an integral part of obtaining credit. At the end of the lesson, all students always obtain an assignment for homework within the course with a topic for the following lesson. Students will be asked questions about the issue at the beginning of the exercise. In case of fundamental ignorance, the student cannot complete the exercise.

Exam evaluation:

A student can register for the exam only if he / she obtains credit. The exam consists of a written part (test), which consists of questions of the MCQ type for 1 point (choice of three options and there is always one correct answer) for a correctly prepared answer, for all other answers, ie wrong, none, badly corrected or multiple , is zero points. Corrections are only possible in the prescribed manner (see instructions on the test and before the test) for MCQ type questions and only one correction is possible for each question. Furthermore, open questions are used in the test, resp. solution of assigned tasks (calculations, proposals, block diagrams, graphs, waveforms, descriptions, etc.) with the fact that a correctly prepared answer is for a maximum of 5 points. Everything is in accordance with the stated test circuits. There are a total of 36 questions (20 ABC types of 1 point each and 16 open ones of max. 5 points - examples, block diagrams, work with catalog sheets, electrical circuits and connections, etc.). Time fortest is 120 minutes. With the number of points at the interface of classification levels (plus / minus two points) it is possible to carry out an oral examination according to the announced test topics. The overall evaluation is awarded according to the number of points from the exam test according to the ECTS scale.
