Title: (EN) SYSTEMS AND METHODS FOR DETERMINING INERTIAL PARAMETERS USING INTEGRATION
(ZH) 用于使用脉冲流的积分确定惯性参数的系统和方法
Abstract: front page image
(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.
(ZH) 本文公开了用于积分以确定惯性参数的系统和方法。谐振器(104)产生基于惯性参数的输入脉冲流(109)。窗口电路(116)选择输入脉冲流的一部分。异或电路(120)使用异或操作将所选部分(118)与参考脉冲流(144)组合以产生组合脉冲流(122)。计数器(124)基于组合脉冲流(122)来递增计数。乘法器电路(154)对递增的计数进行缩放以产生与惯性参数相对应的输出信号(156)。
