We usually "can" make stray C moot. Fender did. Other designers used tubes at 270K even 470K loading and these do show fall-off even within the guitar's limited range, which might be variable with signal. (I don't think it is a major effect.) Yes FETs are NOT Triodes and not ...
HOW DO TRANSISTORS WORK? PART II©1995William J. Beaty, BSEE Physics? That's where you find new insights on things people have been thinking about for a long time. If you don't have two or three separate approaches to explaining something, then you don't really understand it. ...
Instead, you could do it through arelay. But even the relay usually needs more current than the pin can provide. So you’d need a transistor to control the relay: Connect left side of the resistor to an output pin (ex from Arduino) to control the relay But transistors are also useful ...
an electrical circuit built around aninverting operational amplifier. The inverting amplifier is a complex semiconductor device, made up of a number of transistors, resistors and capacitors. The details of its operation would fill an entire article by itself, but here we can get a general sense ...
Transistors had many advantages: high reliability, low power consumption and small size compared to tubes or relays. These transistors were discrete devices, meaning that each transistor was a separate device. Each one came in a little metal can about the size of a pea with three wires attached...
If you have understood correctly, how to use transistors in circuits, you might have already conquered half of electronics and its principles. In this post we make an effort in this direction. Contentshide 1Introduction 2How to use Transistors like a Switch ...
What role (if any) do books have?This interview, which we published before the rise of generative AI, might give us a window. 编辑注:我们即将迎来ChatGPT发布一周年纪念日,这是一台与以往任何机器都不同的知识和信息机器。在我们反思知识的作用时,我们也在思考学习的未来会是什么样子。在人工智能时代...
Encapsidation of subgenomic RNAs results in shorter VLPs (32–40 nm), which typically make up only a small proportion of the virus population [215,216,217,218]. The straight, rod- (precisely: tube-)-shaped particles have a helical organization and are built from the viral genomic ssRNA ...
Others have mentioned that if you break open a 1N34 glass diode to expose the Germanium chip, you can make a crude transistor with a similar procedure. Old Germanium audio power transistors probably do the same, while giving much larger semiconductor area on which to play. Crystal Triode Acti...
