The mouse-over menu allows also to apply a filter to the displayed signals. The filtering settings are
located on the bottom of the mouse-over menu and can be set independently for each displayed
signal of each graph. The available settings are:
•
Filter topology – allows the user to turn ON and OFF the filtering and to select the optimum
filter band-form.
•
Filter type – allows to select the filter type between Low-pass, High-pass, Band-pass, Band-
stop.
•
Order – allows to control the filter order. Higher values of filter order will result in a filter
approaching and ideal behaviour.
•
Cut-off frequencies – controls the cut- off frequencies of the filter. If the “Filter type” is set to
“High - pass” or “Low - pass” the second frequency control is automatically disabled and
greyed out.
As mentioned before, note that each signal of each graph can be filtered independently. This allows
for example to display at the same time in two different graphs the pristine and the filtered signals of
a specific sensor. When a filter is applied to a sensor, a string indicator
“ (S fil) ” will appear on the ri ght
of the sensor name on the mouse-over menu.
Note that the filters are applied only to the signal displayed by the software. The signals recorded
into files and the analog outputs ones are always pristine signals.
