How much information does your microscope transmit?

  • Typical objectives 1x - 5x, about 200 Mpix!

  • on a very good EMG recording the signal-to-noise is 65db ~= 11 bits
  • dynamic range of 5uv to 10mv.
  • differential measurement essential.
  • googling 'EMG bandwidth' yields something around 20-500hz. study of this question
  • delsys wireless EMG system & logger - uses WLAN to transmit the data (up to 16 channels) passband 20-450hz, has QVGA screen, 1GB removable storage.
  • also see "grasp recognition from myoelectric signals" images/474_1.pdf

Above, FCC limitations on UWB transmitted power levels in communication devices. Currently, only the US allows operation of UWB transceivers.
