Yes, it is....!
In RF technology it is very common to use a plane as a single grounding point. It is a very satisfying replacement for the single-grounding-point solution. The ground layer in any multi-layer PCB is such a single-plane-ground, with similar electrical properties to the "old school" single ground concept at both RF and AF frequencies. I would re-formulate the statement in that it is impossible to connect 2 ground points , planes or structures using a single wire/connection. Both Doug and Bill are also right of course from their point of concept/view. Regards, Ing.

Thus the lower cutoff in the "regulations" of 9 kHz. And that is really old school... ________________________________ From: Doug Smith <[email protected]> To: Si-List <[email protected]>; emc-pstc <[email protected]> Sent: Tuesday, April 10, 2012 8:05 PM Subject: Single Point Grounding - Not Achievable at High Frequencies (greater than a few MHz) Hi All, I have just uploaded the first Technical Tidbit article from my new office in Boulder City, NV! Here it is: Technical Tidbit - April 2012 Single Point Grounding - Not Achievable at High Frequencies (greater than a few MHz) The link to the article is: http://emcesd.com/tt2012/tt041012.htm My new office in Boulder City, NV is officially open!!! Still more work to do on the house move so the next few weeks will be very busy and the May Technical Tidbit may be a little late as well. Once the move is complete, I expect to do morning 5 to 10 minute podcasts on technical topics every morning I am in the office. These podcasts will appear on the home page of http://CircuitAdvisor.com <http://circuitadvisor.com/> by late morning each day except for days when I am not in the office.
