Abstract :The Hadronic Calorimeter insert ignore into journalissuearticles values(HCAL); in the CMS experiment at the Large Hadron Collider insert ignore into journalissuearticles values(LHC); at CERN has been designed to measure the energy of jets which are the signature of quark and gluons produced in strong interactions. The jet measurements is the crucial importance for both detector performance and studies Standard Model insert ignore into journalissuearticles values(SM); and Beyond the Standard Model insert ignore into journalissuearticles values(BSM); physics analyses such as supersymetry insert ignore into journalissuearticles values(SUSY);, Higgs boson and heavy gauge boson researches. The other important feature of jet measurements is that it tests the performance of simulated proton-proton insert ignore into journalissuearticles values(pp); collision data produced with Monte Carlo insert ignore into journalissuearticles values(MC); simulations. Precise and accurate measurement of jets of great importance in HCAL especially in central region of the calorimeter insert ignore into journalissuearticles values(|η|<3.0); and concerns many physics analyzes performed in the CMS experiment. Very large aberrant GeV-TeV scale noise is detected in the Hadronic Barrel insert ignore into journalissuearticles values(HB);and Hadronic Endcap insert ignore into journalissuearticles values(HE); sub-detectors located in the central area of HCAL, and it was understood that these GeV-TeV scale noise is not caused by pedestal and other noises. The GeV-TeV scale noise is due to the Front-End Readout Systems in the HB and HE calorimeters. The characteristics and analysis of the noise originating from the GeV-TeV scale Front-End Readout Systems in the HB and HE calorimeters are presented in this study for both 0 \`T\` and 3.8 T magnetic field.
