In this thesis the prototype system for processing of the signals generated in the straw tube trackers of the PANDA spectrometer is proposed, built and evaluated. The full processing chain of signal consists of programmable readout electronics, configware and analysis methods. The proposed readout is based on the front end electronics, equipped with the configurable PASTTRECv1 ASIC (PANDA STT REadout Chip version 1 Application Specific Integrated Circuit) and the readout board (TRBv3 - Trigger Readout Board version 3) acting as data concentrator and time measurement device. The readout system performs full chain of data processing consisting of analog shaping, digital conversion and data transmission. A dedicated analysis methods have been developed to extract track position and a particle energy deposit in the detectors. Dedicated tests of the system by means of the cosmic rays and proton beams have been performed. The results prove that the spatial resolution better than 150 m can be achieved. Furthermore, particle identification based on time over threshold method can be successfully applied in the momentum region below 800 MeV/c. The last but not least goal was to show that it is possible to realize complete readout system based on the concept presented in this thesis which is capable of cope with the hit rates of the PANDA spectrometer.
