Signal processing
5.1 General information on signal processing
The signal processing of the module consists of several steps
shown in this section, i.e. how low-pass filter and oversam-
pling are implemented in hardware components while other
steps are implemented as firmware functions.

Process data is transferred as value normalized to mV in
"signed int 16" format. The process date corresponds directly
to the values read in at the input. It depends on the gain and
offset calculation. Thus, the conversion to an abstract value
range is omitted. The value can be directly used as voltage
value in the application.
