1. A binary signal encoder, comprising:

  • a source of binary signals; and

    an encoder fed by the source of binary signals for encoding each bit of the binary signals into a bipolar pulse pair and with each of the encoded bits having the same average voltage level, the pulse pair having a level which changes from the average voltage level to a first voltage level, then from the first voltage level to a second voltage level, then from the second level back to the average voltage level and wherein the encoder produces the average voltage level between each successive pair of encoded bits.
