The electical signal from the Ge-detector has now propagated through many components that has both shaped and enhanced the pulse. The energy of intest is of course that deposited by the gamma in the detector. The detector has linear response, so the gaussian-like pulse produced in the main amplifier will have an amplitude proportional with the gamma-energy. Since the detector has a linear response, we have that: </math>E_{\gamma} = a \times ch + b</math>
