Statistics are like a bikini.

During the holiday break at the club I started to put some statistics tests on the Kedok hardware. I coded some statistics math on the Kedok to test the analog to digital converter. By putting a reference signal to the input and storing 1000 samples over 10 sec., I could read the standard deviation, standard error, mean and coefficient of variation. All Kedok units I build in the past have a standard deviation of 1.6 in the readings. So there was some noise on the signal. After some research it seems the source was the battery power converter, after putting some filtering on the power lines, it dropped to zero.

What it reveals is suggestive, but does it conceal something vital like a bikini does? We soon know after some tests by Benjamin.
