Noise Calculation Using the Peak-to-Peak Formula

Figure 43
The drift is first calculated by determining the linear regression using all the
data points in the time range (see
linear regression line is subtracted from all data points within the time range
to give the drift-corrected signal. The peak-to-peak noise is then calculated
using the formula:
N = I
where
N is the peak-to-peak noise,
I
