Title (EN) SYSTEMS AND METHODS FOR DETERMINING INERTIAL PARAMETERS USING INTEGRATION OF PULSE STREAMS
(FR) SYSTÈMES ET PROCÉDÉS DE DÉTERMINATION DE PARAMÈTRES INERTIELS UTILISANT L’INTÉGRATION DE TRAINS D’IMPULSIONS
Abstract:
(EN) System and methods are disclosed herein for integrating to determine inertial parameters. A resonator (104) produces an input pulse stream (109) based on the inertial parameter. A window circuit (116) selects a portion of the input pulse stream. An exclusive-or circuit (120) uses an exclusive-or operation to combine the selected portion (118) with a reference pulse stream (144) to produce a combined pulse stream (122). A counter (124) increments a count based on the combined pulse stream (122). A multiplier circuit (154) scales the incremented count to produce an output signal (156) corresponding to the inertial parameter.
(FR) La présente invention concerne un système et des procédés d’intégration pour déterminer des paramètres inertiels. Un résonateur (104) produit un train d’impulsions d’entrée (109) sur la base du paramètre inertiel. Un circuit de fenêtre (116) sélectionne une partie du train d’impulsions d’entrée. Un circuit ou exclusif (120) utilise une opération ou exclusif pour combiner la partie sélectionnée (118) avec un train d’impulsions de référence (144) pour produire un train d’impulsions combiné (122). Un compteur (124) incrémente un comptage sur la base du train d’impulsions combiné (122). Un circuit multiplicateur (154) met à l’échelle le comptage incrémenté pour produire un signal de sortie (156) correspondant au paramètre inertiel.
