Method and apparatus for selectively increasing, decreasing or leaving unaffected the signal-to-noise ratio of portions of an analog transmission signal. As a result it is possible to increase the signal-to-noise ratio of some analog values, decrease the signal-to-noise ratio of other analog values, and leave the signal-to-noise ratio of the remaining values of a given analog signal, so as to better utilize a transmission channel according to the characteristics of the signal to be transmitted. |
