Abstract
Signals are functions or sequences of numbers which represent information. They show the variation of physical or abstract quantities in dependence on one or more independent variables, like time, space, frequency, or others. This chapter serves as a first introduction to the rich world of different kinds of multidimensional signals. It gives an overview on various types of one- and multidimensional signals, presents signals on bounded and unbounded domains, and discusses the influence of initial conditions and of boundary conditions.
