The oscillator is an analogue circuit driving the transistor in its linear mode ... a TV service manual or two and maybe add a 555 as a pulse generator! But aside from that, the elegant hack ...

It’s a surprisingly complex circuit with a lot of filter components and a mild mystery surrounding the use of a GPIO to pulse the receive ... coupled to a two transistor buffer pumping a tuned ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

A transistor that operates with photons rather ... In optics, the output and input wavelengths, beam shapes and pulse shapes should be compatible. Fan-out. The output of one stage must be ...

When the germanium heated up -- a natural outcome of being part of an electrical circuit -- the transistor would have too many free electrons. Since a transistor only works because it has a ...
