发明名称 Method and apparatus for encoding digital data so as to reduce the D.C. and low frequency content of the signal
摘要 An encoding system in which starting from the Miller code a specific word type in the bit series is detected and two bits within said word type are encoded in a different manner in order to obtain an information signal without d.c. component. Moreover, an encoding device, a record carrier provided with such an information signal and a read apparatus provided with a suitable decoding device are described.
