This work deals with the analysis of pulse modulation issues, work is divided into six chapters. The first chapter of the thesis deals with pulse modulations as a whole. It explains the concept of modulation, the distinction between analog and digital modulation, and there is the basic classification of pulse modulation done. The second chapter focuses on the issue of non-quantized pulse modulation. For each modulation belonging to this group is verbally and graphically explains the principle of its activities. In the third chapter, which is similar to the second chapter, the work focuses on quantized pulse modulation. Again, each of these modulations explained its basic principle. It is also in this chapter outlines the design models in Matlab-Simulink. The fourth chapter presents calculations and tables with calculated values needed for simulations. In the fifth chapter, a comparison waveforms. It contains a discussion about the dependence of modulation on their parameters, parameters of the input signal and the sampling frequency. In the final sixth chapter deals with the early design concepts and detailed diagrams for the production of demonstration products.
