Recursive-type periodic temporal signal generator

摘要

The temporal signal generated has a periodic configuration defined by an arrangement of seed patterns resulting from a branching construction employing n successive applications of m pattern type laws each defined by a specific arrangement of p pattern types. This construction amounts to defining a periodic signal configuration as a component "an" of the nth term Un with several components (an, bn) of a recurrent sequence defined at the level of its components by a particular recurrent composition law, the initial term UO having for its components the seed patterns (aO, bO). The temporal signals known by the name "fractal" result from a branching construction of this kind. The generator comprises an elementary signal forms generator circuit (20) corresponding to the definitions of the seed patterns, an m-digit counter (30) to base p incremented when each elementary signal form is delivered by the elementary forms generator circuit (20) and a pattern type selector circuit (40) controlled by the counter (30) to base p and controlling the elementary forms generator circuit (20).
