re receiver system one thing to consider is time division multiplexing the emg channels to reduce the number of rf carriers you have to generate if you multiplexed the emg inputs at khz that would probably be sufficient for most physiology studies you d have hz per channel sampling rate that level of analog multiplexing should be rather easy to accomplish combining a lot of rf carriers is pretty tricky to do without generating intermodulation a system to be carried by a runner is in a fairly harsh environment and would probably be difficult to keep balanced a commercial hand held transciever could probably be employed with a little modification to accomodate widening the bandwidth obviously this has to be done in accordance with whatever laws govern the use of transeivers in your location bill mayhew neoucom computer services department rootstown oh usa phone wtm uhura neoucom edu n wed
