Abstract (en)
The method involves generating compound functions composed of elementary functions, by using programmed units. Compound functions are operated on a reference signal with units that process elementary functions as executable operators. A correlation between compound functions values and a global characteristic value of a reference signal is determined to select an extraction function (4) with high correlation. The programmed units handle the elementary functions as symbolic objects and as executable operators. Independent claims are also included for the following: (a) a apparatus for generating a general function that can operate on an input signal (Sx) to extract a preset global characteristic value (DVex) expressing a feature of the information (De) conveyed by that signal (b) a software product containing executable code which, when loaded in a data processing apparatus, enables the latter to perform the method of generating a general extraction function.
