Analýza digitálně modulovaných signálů

Abstract

This thesis describes digitally modulated signals and use of digitally modulated signal in the modern telecommunications networks. Various factors that degrade the signal in the real transmission channel are analyzed here. The thesis also discusses about the equipment and tools that are used to measure the digitally modulated signals, and also thesis comparison between classical and virtual instrumentation. The thesis shows a flowchart of the analysis of digitally modulated system. The practical part of the thesis is focused on the development and design application that is used to analyze the digitally modulated signals. The thesis subsequently proposed several measurements of degradation effects, which affect the digitally modulated signal by using the designed application.
