Abstract

Transmission of parallel binary signals over short distances (i.e., implant) in a low-noise environment may be accomplished economically, by applying the signals to variably weighted inputs of an algebraic summing circuit 3. The resulting analog composite will have unique amplitude and may be carried over a short distance on a single line.

In Plant Data Transmission

Transmission of parallel binary signals over short distances (i.e., implant) in a low-noise environment may be accomplished economically, by applying the signals to variably weighted inputs of an algebraic summing circuit 3. The resulting analog composite will have unique amplitude and may be carried over a short distance on a single line.

Multiple comparators 4 "measure" the amplitude of the composite and translate it to a unique parallel binary pulse set, corresponding to the inputs to the summing circuit. The weighting functions Z1, Z2,...Zn at the summing input may be arranged in a binary progression, to provide an unique output for each possible configuration of inputs.

Obviously, the composite produced by the weighted summation may also be applied as a modulation input parameter (e.g., for pulse position modulation or other suitable time or phase displacement modulation) for use in long-distance transmission. The remote receiver should be arranged to demodulate the composite information and translate it into the associated parallel binary signal group.
