Digital modulating/demodulating method and apparatus using same

Image Number 16 for United States Patent #5638064.

Digital modulating method and apparatus are provided which converts m-bit data codes, in sequence, into digital modulation codes each consisting of n channel bits (n>m) to form a modulation code sequence using connection codes. Bit patterns of portions of the modulation code sequence and the connection codes are changed or additional bit patterns are inserted into the modulation code sequence so as to meet given conditions of a minimum transition interval, a maximum transition interval, and a Digital Sum Value. Demodulating method and apparatus performing a reverse modulation operation are also described.
