Unidentified continous functions are generalized classification for all signals. Author assumes that any unidentified continous function (any signal) as to be either digital (non-archimedian continuum) or analog (archimedian continuum). Author mainly founded a method to indicate a distinction for both continuum models. This method therefore can be used on to all unidentified continous functions in order to identify the continuum models of unidentified continuous functions.
