2 additional examples

[Pascal Olivier Gaggero]

Dear all,

Following last post I would like to introduce 2 additional examples for the configuration files:

   A) A 32-electrode EIT system with measurement of the contact impedance using a dedicated measurement electronic. 

   B) a multi-frequencies EIT system with simultaneous injection and measurement.

We are looking for your feedback! At this stage, it would be particularly interesting to know if this format could accommodate a large palette of systems and architectures.
