N2 - In a calorimeter with silicon readout, operated at the CERN-Proton Synchrotron, the use of a combination of low-Z (Fe) and high-Z (Pb) materials as absorbers allows the transformation of the electron energy distribution of the incident showers in two media with different critical energies via the filtering effect. As a result, a ratio varying from e/π>1 to e/π<1 is obtained as a function of the thickness of high-Z (Pb) material in the absorber, demonstrating the possibility of achieving the compensation condition e/π=1.
