Abstract

PURPOSE: To generate a sequence of codes including no DC component by coding and outputting the coding output and opposite value of one past input value 0 of a state transition.
CONSTITUTION: Data 0, when inputted from input terminal 1, is inverted by NOT circuit 4d into 1 to invert by NAND circuit 8 one past signal 0 stored in FF3. At this time, since AND circuit 5d following circuit 8 is closed, inversion signal 1 of one past signal 0 is outputted to output terminal 2 via OR circuit 6c. When 1 is inputted from terminal 1, on the other hand, 1 is coded by MFM coder 9. In this case, circuit 5d following coder 9 is opened and AND circuit 5e follwing circuit 8 is closed, so that 1 coded by coder 9 will be outputted to terminal 2. Then, initial 0 and final 0 of the state transition at this time in small sequence of 0, 1,...1, 0 is coded by inverting by added transition to remove a DC component.
