Abstract
Frequency filtering is used in many fields. In optics, for example, white light is separated into its components by a prism, the undesired frequencies are masked and the desired ones are allowed to pass through a slit (Fig. 14.1). In this example, the effect of the prism corresponds to the decomposition of a signal by Fourier analysis, and the screen corresponds to a filter.
