Yes exactly, that's what our teachers advised, to use TDM but I'm not exactly sure how to do this. I'm so glad you answered, thank you very much.
Can you perhaps explain to me how to ensemble all this concepts together ? Because so far all I've got is the blocks diagram i described above. I've been analizing I think I've gone a little bit farther since I think I know what the sampling frequency would be. According to Nyquist it should be twice or above the highest frequency on the original signal, am I right ? I would really appreciate all the help you could give me, I'm literally shooting arrows in the dark. Am I missing something, is the diagram complete for what it was intended to be, a multiplxer of bio-medical signals ?
Again, thank you so much for your help !
