Filter apparatus and method for reducing signal noise using multiple signals obtained from a single source

摘要

An apparatus and method directed to an adaptive noise filtering arrangement. The arrangement has the ability to estimate a first set of data for a first time-dependent variable based upon at least two sets of data for two time-dependent variables related to the first time-dependent variable. Additionally, the arrangement has the ability to filter an actual set of data for the first time-dependent variable based upon the first set of data and the actual set of data. The estimated first set of data and filtered actual set of data can be printed or displayed in a graphical format for analysis.
