Title (EN) LINEARIZING CIRCUIT AND ELECTRONIC TIME PIECE USING THE SAME
(FR) CIRCUIT DE LINEARISATION ET PIECE ELECTRONIQUE DE TEMPORISATION UTILISANT CE CIRCUIT
Abstract: front page image
(EN)A linearizing circuit which includes a frequency mixer circuit for mixing at a prescribed ratio, a first frequency varying in response to the variation of a parameter with a second frequency from a reference oscillation source which is independent of the parameter, and an arithmetic circuit for producing an output pulse corresponding to the average period of the output obtained from the mixer circuit, thereby linearizing the parameter output characteristics. This linearizing circuit is installed in an electronic time piece as ambient temperature sensing means, which means senses temperature information to correct a clock signal in accordance with a temperature shift with respect to a reference temperature, thereby to compensate for the temperature change.
(FR)Un circuit de linearisation comprend un circuit melangeur de frequences pour melanger selon un rapport predetermine, une premiere frequence variant en reponse a la variation d"un parametre avec une seconde frequence provenant d"une source d"oscillations de reference qui est independante du parametre, et un circuit arithmetique de production d"une impulsion de sortie correspondant a la periode moyenne de la sortie obtenue du circuit melangeur, de maniere a lineariser les caracteristiques de sortie du parametre. Ce circuit de linearisation est monte dans une piece electronique de temporisation et joue le role de moyen de detection de temperature ambiante, lesquels moyens detectent des informations de temperature pour corriger un signal d"horloge en fonction d"un changement de temperature par rapport a une temperature de reference, de maniere a compenser le changement de temperature.
