1. A system for controlling a group of peripheral devices responsive to variation of a single-channel analog input signal within a range, said system comprising:

  • a single-channel to multi-channel analog-to-analog signal converter for converting said single-channel analog input signal to a plurality of analog signals, said range being partitioned into a plurality of sub-ranges, said analog-to-analog signal converter comprising;

    a plurality of sub-range signal generators, each of said plurality of sub-range signal generators being responsive to said analog input signal within a sub-range of the plurality of sub-ranges to generate a sub-range analog signal,a data buss having a plurality of buss lines, each of the buss lines being operatively connected to each one peripheral device of the group of peripheral devices for controlling operation thereof, anda unidirectional coupling unit, said uni-directional coupling unit operatively transmitting each of said plurality of sub-range analog signals to at least one of a plurality of buss lines of the data buss and inhibiting any feedback from said buss being transmitted to said analog-to-analog signal converter.
