Signal Processing in High Energy Physics Introduction Signal Processing is a way of converting an obscure signal into useful information Signal processing includes signal formation due to a particle passage within a detector, signal amplification, signal shaping(filtering) and readout The basic goal is to extract the desired and pertinent information from the obscuring factors (e.g. noise, pile-up) The two quantities of greatest importance to be extracted from detector signals are amplitude energy, nature of the particle, localization time of occurrence localization, nature of the particle Luciano musaBeijing, January 2008 Luciano Musa 2 Signal Processing in High Energy Physics Introduction ▪ Signal Processing is a way of converting an obscure signal into useful information ▪ Signal processing includes signal formation due to a particle passage within a detector, signal amplification, signal shaping (filtering) and readout ▪ The basic goal is to extract the desired and pertinent information from the obscuring factors (e.g. noise, pile-up) ▪ The two quantities of greatest importance to be extracted from detector signals are: • amplitude: energy, nature of the particle, localization • time of occurrence: localization, nature of the particle
