ABSTRACT:
An encoder encodes a communication signal including a precorder that precodes portions of the communication signal. The portions comprise a plurality of bits. A buffer buffers said portions. A DC tracking device modulates a flip signal based on a comparison of a DC value of one of the portions of the communication signal and a weighted average DC value of a plurality of previous portions of the communication signal. A flip device selectively flips said portions based on the flip signal.
