Signal splitting effect analysis on SNR and jitter requirement for Muon Tracker Detector

Signal splitting strategy is one of the methods to get implement circuit that gets real-time trigger timing information in addition to post trigger amplitude information in current muon tracker detector. Although signal splitting strategy is cost effective and need short development time, there can be degradation in SNR and jitter and it is needed to analyze the signal splitting effect on the original amplitude signal path and newly added timing signal path to ensure both signal paths requirements are met. This paper analyzes the relations between the signal splitting elements, the coupling capacitors, and the two signal paths requirements. The requirements are signal to noise ratio parameter for the amplitude signal path and jitter parameter for the timing signal path. The results and approach of this paper can be applied to other signal splitting applications to check the feasibility and to set correct splitting ratio which meets the multiple requirements of the application.
