Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified ...
A new type of transistor is being developed by scientists at the NASA Ames Research Center that meshes together the best aspect of semiconductors and traditional vacuum-tube technology. This ...
A vacuum tube, known as the first electronic device, is used to switch, amplify, or commutate electric signals. In the past, vacuum tubes functioned as a main part of a diverse range of electronic ...
Why might an engineer use a vacuum tube over a solid-state transistor? This question is especially interesting since most engineers graduating today do not have a background in vacuum tube circuit ...
