Abstract

On synthétise un signal triangulaire de fréquence nf à partir d'un signal sinusoïdal à n phases R, Y, B de fréquence fondamentale f, en détectant le moment auquel un segment de l'une quelconque des n phases du signal sinusoïdal est compris dans une plage angulaire prédéterminée par rapport un niveau de référence, et en assemblant des segments détectés successifs Y1, Y2, R1, R 2 ,...A triangular signal of frequency nf is synthesized from a sinusoidal signal with n phases R, Y, B of fundamental frequency f, by detecting the moment at which a segment of any of the n phases of the sinusoidal signal is included in a predetermined angular range relative to a reference level, and by assembling successive detected segments Y1, Y2, R1, R 2, ...
