Digital Baseband Transmission - TikZ Figures

Line-code waveforms for the common sequence 1\,0\,0\,0\,0\,1\,1\,0, time-aligned to the bit grid. Plain AMI leaves the four-zero run transition-free; because one ordinary mark (+) has occurred since the last violation (odd count) HDB3 substitutes 000V with V=+, a bipolar violation

Regenerative repeater: an equalizer reshapes the distorted input, recovered clock retimes the decision, and a decision circuit regenerates clean pulses. Below: noisy received waveform, the regenerated clean output, and an E1 PCM frame (32 timeslots; TS0 sync, TS16 signalling)
