Filter driven DC-free codes |
摘要 |
An encoder for encoding a communication signal includes a signal buffer to buffer data associated with the communication signal. A DC-Check circuit to compute a metric as a function of the data. A DC tracking block to generate a flip signal as a function of the metric, the flip signal having a flip state and a nonflip state. A flip unit, responsive to the flip signal, to control a flip bit of an output of the signal buffer such that an average DC value of the data approaches zero.
