In case that multiple Spectral bands associated with a parameter have overlapped
frequency ranges they will be taken into consideration only once on the calculation of the
parameter
Additionally, the system is able to calculate one or multiple
Spectral bands
, in the same way as
explained earlier, but whose value will be subtracted from the value calculated on the field
Spectral
band
. This makes it possible for example to create a parameter that monitors the evolution of the
difference between 2 particular frequencies or bands. This is done by the field
Subtracting spectral
band
and is defined the same way as the field
Spectral band
.
The following image and table show and describes the different fields of the configuration page of this
type of
Parameter
.
