Creating Sum Curve (merge) and Add this curve:
Create sum curve will generate a single curve based on the total average of the individual sweeps of the
two selected curves.
The Sum curve will contain the two merged curves recording sweeps and in this way an improved SNR
1
is
reached. The SNR improves by the formula
�
. .
Instead of merging the curves together to one curve – a third curve can instead be generated.
Add this curve will combine the two selected curve into a third curve based on the total average of the indi-
vidual sweeps of the two selected curves. The added curve will be labelled with an “a” in the handle e.g. 60a
(as shown below). Note New Fmp and Residual noise values are calculated for the combined/merged curve.
However, the graph showing how the Fmp and Residual noise figures change with the number of epochs will
not be available.

SNR = Signal to Noise Ratio – the higher the SNR number the better the signal to noise ratio.
