Abstract

Very often the diagnostics and corrections of an accelerator require the analysis and processing of time varying signals. This is, of course, a scientific discipline in itself which is covered in many textbooks[1–4]. In this lecture, we shall concentrate on two aspects of this discipline, seen from the accelerator specialist's point of view, namely: frequency analysis and signal filtering.
