Σύνταξη εργαστηριακών ασκήσεων τηλεπικοινωνιακών συστημάτων.

Abstract

Η παρούσα πτυχιακή έχει σκοπό: • Tην κατασκευή μιας εργαστηριακής πλακέτας όπου θα πραγματοποιούνται όλες οι ασκήσεις που χρειάζονται πλακέτα (Διαμόρφωση πλάτους, Αποδιαμόρφωση πλάτους, Διαμόρφωση συχνότητας και Διαμόρφωση FSK, PSK, ASK). • Την προσαρμογή των εργαστηριακών ασκήσεων σύμφωνα με την καινούργια πλακέτα και την βελτιστοποίηση των εργαστηριακών ασκήσεων για καλύτερη κατανόηση από τους σπουδαστές.

This thesis is relevant with the optimization of the laboratory of the subject Telecommunication System. This subject is tought in the second semester of the Department of Applied Informatics and Multimedia of the School of Applied Technology of Technological Educational Institute of Crete. In the subject carry out a number of exercises which cover the following issues: • Spectral analysis • Study of filters • AM modulation- demodulation • FM modulation -demodulation • Converter A/D • Modulation PCM • Modulation Delta • Simulation of converter A/D using simulator Spice • Using of software MatLab for simulation of telecommunication system • Simulation of telecommunications system FM • Simulation of telecommunications system PCM The students separated in groups of three persons and every day they materialize an exercise. Some of the exercises need a specific laboratory board. There was a problem because there were not enough boards for all students to make the same exercise the same day. Also the professor could not prepare and tought all the students at the same time. For this reason was necessary the development of a new laboratory board. By using this board all the laboratory exercises will materialized. My personal operation were the development of the frontage of laboratory board, the final control of the electronic features and the adaptation of the pre-existent exercises according to its faction.
