In this paper, an algorithm for real-time analysis of the COMET experiment calorimeter is described. In order to ensure the stable operation of the detector's information reading system, it is necessary to make a decision to start basing on the information from the calorimeter. At the same time, it is required to provide energy resolution in real time no worse than 5 %. On the basis of the simulation results a signal processing algorithm for determination in real time of the energy deposited by incident particles in the calorimeter based on the digitization of signals and their analysis in programmed logic in the traveling wave mode has been developed and optimized. The proposed algorithm was tested by Monte-Carlo simulation, test-bench measurements and electron beam experiments. The results satisfy to the experimental requirements.
