Abstract
A generator of a pseudoperiodic logic signal of mean period Tmean includes: a reference clock of period Tref, a logic memory, changing state on receipt of a pulse, a first mechanism producing a normal pulse on completion of a base time interval Tsec=K×T ref, with K an integer, a second mechanism producing a shifted pulse on completion of a modified time interval T′sec=(K±1)×Tref, and a selector capable of selecting the mechanism that produces the pulse, in such a way as to regularly include a shifted pulse so as to correct the mean period, to generate a pseudoperiodic signal. Such a generator may find application, as an example, to driving a resonator for producing a plasma spark for radiofrequency ignition.
