Summary

Students are acquainted with principles of transfer of informations, with modern modulations principles and their election on design of wireless communications systems applied in control technics. In subject Radiocommunications in control systems students will deepen knowledge from subjects Signals and systems I and II, acquaint with new informations from field processing and transmission of signal. Subject Radiocommunications in control systems have applycation orientation. Teaching are split in three fundamental areas: Fundamental modulations principles (AM, DSB-SC, FM, NBFM), apply capabilities, Modern principles (FSK, SS-DS,SS-FH) and methodology their coparing. Principles of selection of wireless communication systems to control of technological processes.

Way of continuous check of knowledge in the course of semester

Verification of study: Independent parts, laboratory measurements: Measurements in framework elaborate of independent parts také students in working-groups (pairs). Working group is for purposes of preparation to parts, own measurements and processing of results considered as fundamental and indivisible complex. Out of him rsulting, but that their members are in identical style evaluated. In case of absence some of members of working-goup execute all discretions and duties residual members of working-group. Tests. Date, hour and place of practise all tests be to students at least of two weeks adwance reported. Student, that from documentary, objective argumnets can not at regular term arrived, may be enter to alternate term as to reagular. In case of any alternation of tests terms, it will be to students imediately reported at lessons or practise. In writing will be at side palne on the gallery beside room A423 presented. Conditions for credit: minimal 24 pionts (max. 50points) and meet deadlines of laboratory practices Test specifications Test of continuous preparation of students and final test is working out of usage of literature, notices and study tools. Requirement is self-work of student. In case of helpless work of student is test evaluated with zero points. Specifications of credit: Credit acqiure a student, that receive per practice minimal 24 points and fill specifications of laboratory practices, this means in rated deadlines commit content and formaly rightly elaborate independent parts nr.1 and nr.2 during semester.
