摘要：

For an efficient data talking, the Electromagnetic Calorimeter (ECAL) data of the CMS experiment must be limited to 10% of the full event size (INS). Other requirements limit the average data size to 2kB per data acquisition link. These conditions imply a reduction factor of close to twenty on the data collected. The data filtering in the readout of the ECAL detector is discussed. Test beam data are used to study the digital filtering applied in the readout channels and a full detector simulation allows to estimate the energy thresholds to achieve the desired data suppression factor.
