Due to the ubiquitous presence of interference and a need for a large angular resolution, the current radioastronomical observations are carried out using multi-antenae receiver systems. Construction of such devices places great demands upon the quality of signal processing. A source of inspiration for my diploma thesis has been my own amateur radioastronomical activity in the field of meteor observations.
The thesis deals with a possible realization of a digitalization unit for a radioastronomical signal receiver. The implementation described in the thesis is optimized for a high dynamic range and good phase stability, both being the most important parameters for its application in the multi-antenae systems. Design and the instrument implementation have been created as open-source hardware solutions, so far having unique characteristics among the devices used in amateur or professional radioastronomy.

I have devised and implemented a trial version and made further experiments with it. A resulting recommendations for repeated implementations of the receivers, that we are planing to use in the amateur meteor observing networks, are based on these experiences.
