In the PANDA experiment at the HESR antiproton storage ring of the FAIR facility in Darmstadt (Germany) the central tracker is a key element which will provide information about decay vertices, momenta and the type of charged particle emitted in antiproton annihilation. Various techniques are known for the extraction of energy-loss information from analog signals of gaseous detectors like straw chambers. These include electronical techniques as well as off-line treatment of the data. The main difficulty lies in the poor statistics of the formation of electron-ion clusters and in the strong asymmetry of the Landau distribution. A general-purpose chain of electronics and data acquisition based on sampling ADCs has been developed which permits off-line application of various techniques.
