3105 Signals and Systems<br />
<strong>ECTS</strong> credits: 7<br />
Weekly classes: 3lec+0sem+0labs+2ps+2cw<br />
Assessment: exam<br />
Type of exam: written and oral<br />

Abstract:<br />
The compulsory subject Signals and Systems has the objective to acquaint the students with the main principles in<br />
creating, processing and transferring of electrical signals for the needs of communications, informatics and<br />
automatics. The knowledge of Physics is a course prerequisite.<br />
Course content:<br />
General concepts of the information theory. Electrical signals - types, main characteristics. Spectral analysis of<br />
periodic signals and non-periodic signals. Correlation analysis. Discreteness. Linear conversions of the signals.<br />
Input and output immittance of a quadripole. Analog and digital filtration. Modulation and demodulation. Coding.<br />
Signal conversions. Course assignment - harmonic analysis of periodic and non-periodic signals. Application of<br />
the Naikuist - Kotelnikov theorem. The subject includes a course assignment.<br />
Teaching and assessment:<br />
The lectures last two hours and are delivered according to the following scheme: the first week one lecture with<br />
duration of two hours, the second week two lectures with duration of two hours.<br />
The exercises reflect the lecture material. Manual calculations, study via computer analysis and laboratory<br />
measurements are done during the exercises. The students prepare a report for each exercise. The students do<br />
the course assignment on their own. It helps to consolidate their knowledge about harmonic analysis of periodic<br />
and non-periodic signals and the application of the theorem of Naikuist - Kotelnikov.<br />

Abstract:<br />
The course objective is to provide students with practical skills for working with electrical measuring devices and<br />
for choosing suitable measuring methods in accordance with predefined accuracy. The main tasks include<br />
acquaintance with the main techniques and ways for measuring the parameters and characteristics of the<br />
electrical signals, circuits and devices and principles of measuring devices, systems and interface construction.<br />
Digital measuring devices and programmable measuring circuits with higher metrological characteristics are taken<br />
into consideration.<br />
Course prerequisites include Electrical Measurements, Analog Schematic Circuits, Signals and Systems and the<br />
course itself is a prerequisite for the Pulse Digital Devices, Microprocessors, and other courses, too.<br />
Course content:<br />
Measurement alternators. Sine sources with separate and self-generated excitation. Pulse transducing devices.<br />
Cathode-ray oscilloscope. Kind of oscillographic scans. Waiting scan. Oscillogram distortion. Electronic voltmeters<br />
with effective value converters, effective to mean value converters and maximum value converters. Digital<br />
voltmeters for DC voltage measuring. High and low frequency measuring. Digital meter for signal frequency and<br />
transient parameters measuring. Oscillographic ways of phase difference measuring.<br />
Teaching and assessment:<br />
The teaching is carried out through lectures and practical exercises. The main topics of the lecture material enable<br />
the students to get acquainted theoretically with the general principles, ways and means of measuring of electrical<br />
quantities with electronic devices. The practical exercises have duration of 2 hours weekly according to the<br />
syllabus. Final assessment is based on a written and oral exam.<br />
