摘要: A run-length-limited group coding system is provided wherein the code permits a high data transfer efficiency. Code values for both and control functions are chosen such that maximum cumulative DC deviation from nominal center no more than 10 percent averaged over transmission sequence. The employed limits number of zero bits between successive one in serial binary sequence to predetermined value thereby permitting self-clocking. particularly suitable use baseband systems where medium either an electrical or optical link. meet same constraints as those protocols established may be integrated into variety multiple-unit configurations communication units is, example, by way point-to-point link, bus, star, loop, ring arrangement.
