  1. High-speed Internet – I’m talking data links between continents – is already blazing fast compared to what most people are used to but researchers have found a way to make it even faster by improving the overall reliability of the signal.

    It sounds good. I'm all for anything that speeds up the internet except the cost from my back pocket.

    Uhm.. this is using the exact same principle employed in balanced audio (XLR), humbucker pickups in electric guitars, etc..

    I don't understand the concept of noise canceling a digital signal. When a digital signal is comprised of only 0's and 1's, how can you cancel out interference? It's not as if a third state in binary can be introduced to counter a stray signal.

    Perhaps the answer lies within my confusion of phase conjugation.
  5. The interpreted signal is digital (0's and 1's) but the real signal is analog. When noise is added a binary digit might be interpreted wrong so a dirty zero become a 1 an vice versa. Hope this helps :)
