When hooking up a miniphono jack from my laptop to the airplane's comm system we are able to play music on our headsets while we are flying.
If I plug the power cord into my laptop, we get a loud feedback in our headsets.
The AC powercord is fed from a DC/AC inverter powered from the aircraft (which in turn is turned back into DC before feeding the laptop.)
How can I filter out the noise from that we are receiving in our headsets?
Am I getting this noise because I need to ground the inverter somehow?
Any help would be appreciated.
Thanks.
