1. A monitor for receiving electrical signals from a living body and processing such signals to obtain information relating to a bodily function or organ, said monitor comprising:

  • means for acquiring the electrical signals through one or more electrodes connected to the body, first filtering means for filtering said electrical signals to provide selectively unfiltered signals, said selectively unfiltered signals being unfiltered in a preselected bandwidth greater than the bandwidth into which the electrical signals are expected to fall, said means for acquiring being located within a first housing and including a means for receiving the selectively unfiltered electrical signals in analog form and converting the selectively unfiltered signals into an unfiltered stream of digital signals;

    second filtering means for filtering said stream of digital signals to isolate signals of interest from said stream of digital signals, said second filtering means being located in a second housing separate from a housing in which said means for acquiring is located;

    means for transmitting said unfiltered stream from said means for acquiring to said second filtering means.
