“…Fred and the other young engineers defining a digital transmission system came up with concepts that were critically important to a successful design, addressing problems such as baseline wander (for the decision threshold between "1s" and "0s") and crosstalk between twisted pairs As he reported in his April 2011 T1 history article [1] in IEEE Communications Magazine, "One day the proverbial light bulb went on and we had the idea that solved this [baseline wander] and several other problems. If "1s" were transmitted by alternative positive and negative pulses and a "0" by no pulse, there would be virtually no wander.…”

“…Besonders beeinflusst wurde van der Waals aber von den Messungen von Regnault zur Kompressibilität verschiedener Gase, die 1847 publiziert wurden. [24] Einen großen Einfluss auf seine Arbeit hatten auch die sorgfältigen Messungen der Isothermen von Kohlendioxid oberhalb und unterhalb des kritischen Punkts, über die Thomas Andrews [25] 1869 in einem Artikel berichtete, der fast den gleichen Titel trug wie van der Waals Doktorarbeit. Nicht nur sicherten ihn diese Ergebnisse experimentell ab, um mit sei- …”

“…Der zweite Teil der Dissertation ist der Bestimmung der Konstanten a und b gewidmet und nimmt Regnaults [24] Daten zur Gaskompressibilität und Andrews [25] nur wenige Jahre zuvor ermittelte Isothermen als Grundlage. Die Bedeutung dieser Werte für seine Zustandsgleichung diskutiert er dann in den letzten Abschnitten.…”

“…Shannon's work, however, had a great impact on the adoption of the sampling theorem by the engineering community as a practical engineering tool. For instance, one of the first practical applications of the sampling theorem in communications engineering was the T‐carrier system , a transmission technique predating many of the modern data transmission technologies such as SDH/SONET, all of which are based on PCM (Pulse Code Modulation), a practical idea directly derived from the sampling theorem, as shown in ref. .…”
