Abstract (en)

[origin: WO2008025911A1] Generator of a pseudoperiodic logic signal of mean period T<SUB>mean</SUB> comprising: a reference clock (5) of period T<SUB>ref</SUB>, a logic memory means (6), changing state on receipt of a pulse, a first means (7) for producing a nominal pulse on completion of a base time interval T<SUB>sec</SUB> = K OET<SUB>ref</SUB>, with K an integer, a second means (8) of producing a shifted pulse on completion of a modified time interval T'<SUB>sec</SUB> = (K ± 1) OET<SUB>ref</SUB>, a selector means (10, 12) capable of selectingthe means which produces the pulse, in such a way as to regularly include a shifted pulse so as to correct the mean period, in order to generate a pseudoperiodic signal. Application to the driving of a resonator for producing a plasma spark for radiofrequency ignition.
