View Full Version : TROUBLE WITH EMG AND ELECTROMAGNETIC TILTPLATFORM

Hello !

I'm performing some trials with subjects standing on a tilting platform
wich is released by two 20V DC Electromagnets. The electric source is
different from that supplying power to the EMG preamplifiers. All are
attached to ground. At release I get noise into my EMG signals for more
than 80 ms. So i can't see any reaction times.
The supplying for the electromagnets has two indwelling diods built in.

Any Idea on how to get rid of the noise?


Thanks a lot.


Gaspar Morey.
