✦ Synopsis

The CMD-3 detector includes a magnetic spectrometer and an electromagnetic calorimeter. The calorimeters' signals are used for energy deposition measurement and for triggering. For triggering, the calorimeters' signals are transformed into special short-shaped analog signals. These signals are then digitally processed with special algorithm, which allows one to obtain a set of logic signals necessary for event selection and a time-tag signal for time alignment of time measurements. In this paper, the main features of the developed signal processing algorithm are described.
