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.
