Abstract
A signal generator generates a temporal signal with a periodic configuration defined by an arrangement of seed patterns resulting from a branching construction iteratively using laws for composing several patterns and consisting in defining the periodic configuration of the signal as a component 'a.sub.n ' of the nth term Un with several components (a.sub.n, b.sub.n) of a recurrent sequence defined at the level of each of its components by a specific recurrent composition law, the initial term U0 having for its components the seed patterns (a.sub.0, b.sub.0). The temporal signals known as 'fractal' signals result from a branching construction of this kind. The generator comprises a microprocessor (10) associated with a keyboard-display system (11), a read-only memory (12) for programs, a random access memory (13) and an output digital-to-analog converter (14). When creating a signal periodic configuration pattern its working memory contains at least three files: a current patterns file, a previous patterns file and an old patterns file, the current patterns being constructed from arrangements of old patterns in which the seed patterns have been replaced by the preceding patterns.
