This is the desired EKG output

For the audio card of the XO, an additional step has to be done, an AM
modulation of the signal
 to avoid disruption. (special thanks to the prof  Gustavo Rojas Medina his
hard work has made all this effort possible).

We expect to have more documents on this (Circuit schematics, calculations,
theory and PCB) in the next weeks.

Input and help appreciated

Cheers!
