We also discuss concerns other than speed, in particular, energy efficiency.

Rutger illustrated lots of approaches with samples from some of his many synthesizers.

Diese Episode betrachtet das Fly-by-Wire System des A320 im Detail; in gewisser Weise ist diese Episode eine Fortsetzung der letzten Episode aus anderer Perspektive. Ich unterhalte mich dazu mit Reinhard Reichel vom Institut für Luftfahrtsysteme der Universität Stuttgart. Es geht um die Grundlagen von Fly-by-wire, die Funktionalitäten die es typischerweise zur Verfügung stellt, sowie die Architektur des Systems im A320. Dabei gehen wir auch auf einige Grundlagen von robusten, redundanten Systemen ein.
