  • Process and device for the baseband transcoding of digital information
    Patent number: 6307864
    Abstract: The symbols of a first code are represented by sign and magnitude bits in a manner analogous to the sign and magnitude bits representing the symbols of a second code. A memory stores digital samples partially representing coding pulses, and each pair of sign and magnitude bits is used to control a common shaping filter. The shaping filter uses the samples stored in the memory to generate a sampled digital signal representative of the analog signal transmitted over the telephone line.
