1. An encoder capable of transmitting binary encoded output signals representative of samples of an analog input message signal to the encoder, the encoder comprising:

  • sampling means (10) responsive to an analog input message signal to the encoder for generating samples of the input message signal at a predetermined sampling rate; and

    encoding means (14, 16,

         18) responsive to the samples from said sampling means for encoding each of the received samples into a unique digital number pair signal representative of a quantized version of each received sample, each number pair signal including a first and a second digital number signal comprising M bits each for transmission over a first and a second channel or path, respectively, where predetermined ones of the possible unique digital number pair signals which can be formed by said encoding means comprise different first and second digital number signals and each of the associated first and second digital number signals provide a capability for substantially reconstructing the associated analog input message signal sample at a remote decoder.
