The PANDA experiment at the upcoming FAIR accelerator facility will study antiproton annihilation reactions at antiproton beam momenta from 1.5 GeV/c up to 15 GeV/c. With its modular multi purpose detector system it will be able to observe a variety of physical channels. The electromagnetic process group (EMP) in Mainz is developing the backward end-cap of the electromagnetic calorimeter. Within this activity a method for the real time extraction of specific signal features using the APFEL ASIC preamplifier will be developed for the whole PANDA calorimeter. The feature extraction has to cope a multitude of requirements. It has to be high sensitive to the pulse shape. Furthermore the single channel threshold has to be lower than 3 MeV to be capable of doing the PANDA physics. Due to the high event rate of PANDA a short dead time is needed. The extraction procedure has to be efficient to achieve a short calculation time. In my talk I will point out the latest developments of the feature extraction by presenting promising candidates for the on-line extraction routine.
