Signal Integrity

You have to follow the path of the signals to perform the task of signal integrity inside a system. The TRT has mainly two different kinds of signals - the data signals and the control signals. After the generation inside the straw, the data signal is preprocessed inside the front-end electronics. The encoded digital signal travels forth of the TRT and the Inner Detector over intermediate patch panels to a repeater patch panel and out of the ATLAS detector to the back-end electronics. The control signals travel the other way around - starting at the back-end electronics and ending at the front-end electronics.
