transmitters. A small unit plugs into your electric guitar and rather than drag a long cord around the unit transmits to a receiver that you plug into a guitar amplifier. These were used for microphones too.

Well voice and emg have the same characteristics. We wired emg skin sensors as the guitar sources (2) and the receiver into the left (white) and right (red) video inputs. The recorded video now had L & R emg where sound normally goes. View that video in any (even free) video editor and you have 2 channel emg that is in sync frame by frame. Our video engineers split off a copy of each channel that went frame by frame into the vertical black video signal interval that sits unseen below each video frame. They reprogrammed the video text mechanism [for the deaf] to display a bar alphabet as encoded text superimposed on screen so that we had bar type live emg in the video. This allowed watching the emg as you manually examined and did quick/slow passive movements.
