Computers in Experiments
FSI-TPEAcad. year: 2020/2021
The Computers in Experiment course is primarily devoted to hardware problems of the microcomputer application in experiments and to special software products for controlling the devices and virtual instrumentation. In lectures and laboratory measurements students will get acquainted with ports of the microcomputer (COM), standard interfaces (GPIB, MXI, USB, FireWire), measurement boards and some special electronic circuits (Multiplexer, A/D and D/A converter, Timer and Counter).
Main stress is put on the practical application of these new trends in design and performing the experiment. For the design and realization students will use the multifunction measurement boards and LabVIEW programming environment.
Learning outcomes of the course unit
Performance of the computer-controlled experiment with application of standard interfaces and programming tools. More detailed knowledge of RS232 and GPIB will enable students to solve some particular tasks. Realization of simple virtual instruments in the LabVIEW environment.
Decimal, binary and hexadecimal number system. Fundamentals of the programming in a programming languages (Pascal, Visual Basic, C). PC hardware.

Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
The attendance in the labs seminars, handing over reports from labs measurements. Working-out the individual project. The final evaluation considers the individual project (70%) and laboratory reports (30%).
Language of instruction
The aim of the course is to make students acquainted with basic elements of the computer-controlled experiment. After completing the course students should be able to interconnect the instrument and PC through a standard interface and control these instruments by standard programming tools. We will also pay attention to utilization of the serial port of the PC for generation and detection of binary signals.
Specification of controlled education, way of implementation and compensation for absences
A teacher checks the attendance on seminars stated in the timetable. The form and the date of the compensation of missed lessons are specified by the teacher.
