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. A hybrid analog/digital method of signal transmission includes the steps of obtaining an analog value x1 (22) which is desired to be transmitted, representing the analog value x1 with B1 bit(s) of digital information and an analog value y1 by means of a n~ipping function (28) and transmitting the B1 bit(s) and analog value y1. T he analog value y1 can be decoded using the B1 bit(s) to obtain a representation of the analog value x1. |
