450-4002/02 – Modulated Signals (MoSi)

The course deals with the basic analog and digital bandpass signaling techniques. These are applicable to both the analog and digital communication systems. Next students study basics of the digital signal processing. Amplitude analog modulations and the angle analog modulations schema and algorithms are presented (AM, DSB-SC, SSB-SC, PBSK, PM and FM signals). Digital modulations and their algorithms are presented (OOK, ASK, PSK, FSK, QAM, APSK). Theoretical lectures are followed by the laboratory seminars.

The course Modulated Signals and the Bandpass Signaling is closely related to the courses Signals and Systems, Fundamentals of Signals and Systems Theory and Digital Signals and Systems. It is appointed for students and professionals in electrical engineering, measurement, control, informatics and communications. Student will master the mathematical description and representation of bandpass waveforms and systems, will be acquainted with the basic bandpass signaling techniques. These are applicable to both the analog and digital communication systems. Amplitude analog modulation and the angle analog modulation schema are presented (AM, DSB-SC, SSB-SC, PBSK, PM, FM and NBFM signals). Digital modulations of bandpass signals are presented too (OOK, ASK, PSK, FSK, QAM, APSK, OFDM). The knowledge of mathematics in the extent of the obligatory mathematical course at VŠB TU Ostrava, FEI, is the preliminary for the study of the course. Basics of physics and electrical engineering are useful. The command of the preliminary classes Signals and Systems, Fundamentals of Signals and Systems Theory and Digital Signals and Systems is assumed. Students use measurement equipments for modulated signal analyses. The course Modulated Signals and the Bandpass Signaling deals with a rather large thema in an one-semester course. The physical meaning of the mathematical representation of the signals and systems is always discussed. For the mathematical development of some formulas describing the communication process from the statistical viewpoint is student referred to the literature.

Verification of study: Student must work out two laboratory works. Student can receive up to 10 points for each of project. Maximum number of points student can gain through tests is 2 * 10 = 20 points. Student has to elaborate one test. Student can acquire up to 20 points for it. Student can gain up to 20 + 20 = 40 points from the laboratory excercices. To pass the course student has to pass both the laboratory part of the course and the final exam. the Final exam consists of writing part 0 - 50 points and oral part 0 -10 points. Student have to succeed in all parts of examination (writing part minimal 10 points, oral part minimal 1 point). Conditions for credit: Student must work out two presented laboratory works (minimal limit 5 points) and one test (minimal limit 5 points). To pass the laboratory part of the course student has to gain at least 10 points from the laboratory excercices Students could work on their projects in defined consultation hours at the laboratory and by themself.
