The next generation of 4 \pi arrays for high-precision \gamma -ray spectroscopy AGATA will consist of \gamma -ray tracking detectors. They represent high-fold segmented Ge detectors and a front-end electronics, based on digital signal processing techniques, which allows to extract energy, timing and spatial information on the interactions of a \gamma -ray in the Ge detector by pulse shape analysis of its signals. Utilizing the information on the positions of the interaction points and the energies released at each point the tracks of the \gamma -rays in a Ge shell can be reconstructed in three dimensions on the basis of the Compton-scattering formula.
