Detailed Description

Header file for SCT_Amp Class

A class to model an SCT amplifier and shaper. Gives a CRRC response to a list of charges with times. Also calculates average input and output for diagnostic purposes. Questions/comments to Szymo.nosp@m.n.Ga.nosp@m.domsk.nosp@m.i@ce.nosp@m.rn.ch Name changed from SCTpreamp (misleading) on 09.05.01.
