Line Coding Requirements/Desiderata
◮ Small transmission bandwidth
◮ Power efficiency: as small as possible for required data rate and error probability
◮ Error detection/correction
◮ Suitable power spectral density, e.g., little low frequency content
◮ Timing information: clock must be extracted from data ◮ Transparency: all possible binary sequences can be transmitted
