发明名称 Apparatus And Method For High Resolution Measurements For Downhole Tools
摘要 An apparatus and a method for reducing phase noise in measurement signals from a sensor are provided. The apparatus and method, in one aspect, may use a multiphase counter to obtain a count for each sensor signals time cycle and a filter to reduce noise from the obtained counts. A suitable reference frequency, including the reference frequency of the sensor, may be utilized by the multiphase counter.
