Digital Filter Overview
Applicable to
Filter basics
The RSDM-9060/9061 internal digital filter
converts the analog input signal into digital format
before passing it to internal circuits for processing.
The filter affects the amount of noise included in
the measurement result.
Filter type
The digital filter averages a specific number of
input signal samples to generate one reading. The
filter type defines the averaging method. The
following diagrams highlight the differences
between the Moving and Repeating filter using 4
samples per reading.
Moving
(default)
The Moving filter takes in one new
sample and discards the oldest
sample per reading. This is the default
behavior when the digital filter is not
specified, and is recommended for
most applications.
1 Sample #
1st reading Sample 1 - 4
2nd reading Sample 2 - 5
3 2 4 5 6 7 8 9 10 11 12
3rd reading Sample 3 - 6
Repeating
The Repeating filter renews a whole
group of samples per reading. This
method is recommended when using
the optional scanner.
