The main aim of this is to filter the noise from the signal and to provide a quickly restored baseline. The CR-200 shaping amplifiers have low output impedance (<5 Ohms) and can source/sink 10 mA of output current. CR-110 output impedance is 50 Ohms.[9.]
The whole circuit is presented as commercially available PCBs: CR-150 evaluation board and CR-160 Gaussian shaping amplifier evaluation board (Figure 9, Figure 10).
