* The current clamp only measures AC, so any DC component is an unwanted artifact from the
|
|
* sampling circuit. The AC component is essentially the same as the calculating the Standard-Deviation,
|
|
* which can be done by cumulating 3 values per sample:
|
|
* 1) Number of samples
|
|
* 2) Sum of samples
|
|
* 3) Sum of sample squared
