3-26 Module Data, Status, and Channel Configuration
The table below identifies the number of significant bits used to
represent the input data for each available filter frequency. The
number of significant bits is defined as the number of bits that will
have little or no jitter due to noise, and is used in defining the
effective resolution. Note that the resolutions provided by the filters
apply to the raw/proportional data format only.
