On the feasibility of predicting the ATLAS EM Calorimeter ionization signals using the Time Convolution Method at the LHC sampling rate

The Time Convolution Method was developed to extract the electrical parameters associated with the readout of ionization signals in the EM Calorimeter. It has been developed and was successfully used for the EMC calibration at the 2001/2002 H8 beam test. In this note we investigate the the feasibility of the method at lower sampling rate, down to and including the LHC run-time rate of 25 ns.
