This ambiguity can be overcome by using differential Manchester encoding.
2.
An example of Differential Manchester encoding : Gray vertical lines, full and dotted, represent the two clock tics per bit period.
3.
Is the first " transition " of a differential Manchester encoding signal the first time it deviates from its initial level or the first time it returns to that initial level?
4.
This scheme is called differential Manchester encoding or FM ( Frequency Modulation ) or " 4 and 4 ", and allows only 10 256-byte sectors per track to be recorded on a single-density 5?floppy.
