Laboratory railway model control

This work deals with possibilities of operating signals under the power supply voltage and using of this technology in guidance of a model of railway. Firstly there is an analysis of analogous and digital guidance of the model of railway. There is also a description of theory of three kinds of used modulations such as ASK, FSK and OFDM modulation. There are described only principles of those modulations because the problematic of the modulation is going to be solved by integrated circuit. The next part of this work is going to deal with a market research and with description integrated circuits, which ensure the modulation of operating signals of power supply voltage. There is also going to be noticed a description of others circuits that are needed for the correct function of the whole furnishing. Then I will continue with a project of scheme and single PCB for a guidance of the model of the railway. The last part of this work is concerned with activation and a proof of those proposed linkage
