1. A transmission system for transmitting N, N being an integer, binary input voltage signals, each having a magnitude equal to either a first or a second voltage level and received on N input signal ports, out of a single output port, said system comprising:

  • a clock generating for setting the states of a plurality of clock signals to define a set of M, M being a fixed integer less than N, sequential time slots; and

    a time/voltage concurrent encoder, adapted to receive said N binary signals and said clock signals, for selecting a distinct subset of N/M of said binary input signals and concurrently converting said selected N/M binary signals into a corresponding one of 2**(N/M) discrete predetermined voltage levels during each time slot, with the corresponding voltage level uniquely encoding the values of the selected N/M binary input signals so that the encoded values of said N binary input signals are transmitted out of the single output port during said M sequential time slots.
