One of the basic concepts of signals processing theory, lying in the grounds of signals filtering and detection theory, is an uncertainty function. It is broadly used for signal classes selection in communications, radiolocation and underwater acoustics. In this article it is generalized to build a wideband signal uncertainty function, defined on a two-parametric group of transformations. Some properties and general conditions of its approximation by a narrowband uncertainty function are considered.
