Abstract
An apparatus for encoding a digital signal includes switching means for alternately outputting the digital signal from first and second output terminals at every bit, a first converting means for converting the digital signal output from the first output terminal to a signal which will be DC free after NRZI conversion is carried out, a second converting means for converting the digital signal output from the second output terminal to a signal which will be DC free, and an encoding means supplied with outputs from the first and second converting means, alternately combining outputs of the first and second converting means at every bit and obtaining a substantially I-NRZI converted digital signal.
