description This thesis reports the analysis of contributions to noise in the data readout for Trigger Tracker in the LHCb experiment. Measurements have shown that some specific data channels have more noise than the others. This additional contributions to noise cannot be explained by basic electronic noise principles of the detector but by noise sources in the readout chain. The focus is on the channels near the header. Because of a crosstalk effect in the readout electronics the pseudo- digital header affects the close-by analog data channels. Therefore the correlation between the header and the data channels is studied precisely by self-made analysis tools in order to develop an algorithm that cancels the crosstalk contribution to noise. Thanks the algorithm the noise can be reduced efficiently.
