Měření modulovaných signálů osciloskopem a spektrálním analyzátorem – laboratorní úloha

Abstract

This thesis deals with three drafts for laboratory excersise. There are amplitude, frequency and pulse width modulation. In this thesis, there are theorethical and mathematical analysis. There are also described some advantages, disadvantages and differencies between these modulations, including their electric circles. In theoretical analysis, there are mentioned principales of modulations with their possibilities of using in practice. In this part, there are also described things connected with tuning and testing of these modulations.In pratical analysis, there is described the process of the development of AM, FM and PWM modulator. There is also mentiod thein solution in EAGLE software.All manufactured parts of this thesis were tuned and tested on solder field. All PCB was also tested to get some information about its corectness. From all these things, there was created the laboratory excersise for using in practical lessons. In the end of this thesis, there are evaluated all results.
