This is well suited to vacuum tubes but not so much for solid-state. Cost – When it comes to cost, solid-state amplification really shines. Things like transistors, FET’s, rectifiers and integrated circuits are all machine made in enormous quantities using high-speed assembly lines. This ...
Occasionally there are jumps in technology, like the shift from vacuum tubes to transistors, but mostly there are a lot of small tweaks that just make everything a little easier or faster or cheaper. All that technology; if you take a chunk of it away, or if major parts of it fail, ...
Clay in person, at Matt Asay and Bryce Roberts’s Open Source Business Conference in 2004, he retold the story of how RCA had spent billions of dollars in current value trying without success to make the radio and television sound quality of transistors as good as that of vacuum ...
The study of microphone impedance converters goes much deeper than this explanation, but that is for a different article. The goal here was to let you know that tubes and transistors are required in condenser microphones due to the high impedance of the condenser capsule. For more information on...
moved in a straight line from here to net zero by that year – which it won’t, since 70% of the world is moving in a straight line in the opposite direction, and the remaining 30% are finding it a lot more difficult and expensive to attain net zero than they had originally ...
Today, we can see Turing’s vision writ large. Digital technology pervades just about everything we do, from producing documents to navigating the physical world. Although the basic technology has evolved from vacuum tubes to transistors to integrated circuits, modern computers are essentially scaled...
Solutions containing the virus, with a density of about 1.3 g/mL in the case of TMV, are layered on top of the gradient, and the virus particles are centrifuged into the gradient for 1–3 h, depending on centrifugal force. As the density of the gradient material is lower than that of...
The transistor was much smaller and used less power than vacuum tubes and ushered in an era of cheap small electronic devices. 1957: SpaceflightThe Soviet Union surprised the world on October 4, when it launched the first artificial satellite, Sputnik 1, a small 83.6-kg (184.3-pound) metal ...
Ask anyone who is learning English as a second language what they think the most-maddening oddity of the language is and you are bound to get several different answers (there are, after all, dozens of exceptions to the “rules” of English). But here’s one that repeatedly comes up, eve...
