Abstract

The representation of information by waves is common to many fields in engineering and physics like electromagnetism, acoustics, and optics. Many different tools for the description of wave-like signals have been developed. Most of them are based on methods and results from mathematical physics with different viewpoints according to the specific application areas. This paper presents a framework for some of the most common of these representations. It is based on well-known transform domain signal descriptions from linear systems theory.
