This chapter explores signal processing, a subject with applications in diverse branches of science and engineering. A signal in this context can be a quantity that varies in time (temporal signal) or as a function of space coordinates (spatial signal). An audio signal is a typical example of a temporal signal, while an image is a typical example of a spatial signal in two dimensions. In practice, signals are often continuous functions. But it is common in computational applications to work with discretized signals, ...
