A method and apparatus for single signal, multiple channel digital information transfer through waves with time slot allocation. The apparatus consists of one or more transmitting devices and one or more receiving devices. Multiple source signals are each allocated a unique time slot between successive synchronization waves. Digital signals from each source are converted to analog information waves having a positive wave segment and a negative wave segment. The ratio of the amplitude of the positive wave segment to the amplitude of the negative wave segment, the positive-to-negative ratio, for each signal source, is a function of the magnitude of the source digital. The sum of the amplitude of the positive wave segment and the absolute value of the amplitude of the negative wave segment, the positive-to-negative offset, is maintained at a pre-set value at transmission. The total signal, which consists of successive synchronization waves interspersed with information waves for each signal source, each within its allocated time slot, is transmitted to the receivers which extract the positive-to-negative ratio and positive-to-negative offset for each signal source, calibrate the received signals and generate output signals which reproduce the transmitted inputs.
