informationwidthbased
Informationwidthbased is a theoretical construct in information theory that describes a family of measures aimed at quantifying information content relative to the width of a signal or resource used to convey it. Width can be interpreted as temporal duration, spectral bandwidth, spatial extent, or other resource dimensions. The central idea is to assess information efficiency by normalizing information by width, producing units such as bits per second per Hz or bits per second, depending on the width choice.
Definition and variants. A common formulation considers a stochastic process X(t) observed over a window of
Properties. Informationwidthbased measures are nonnegative and generally scale with information content while inversely relating to the
Applications. The notion is used in theoretical analyses of communication systems under resource constraints, in data
