Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

I don’t have a signal generator, or more specifically I don’t have a low frequency signal generator or a function generator. Recently this fact collided with my innocent pleasure in buying cheap stuff ...

The circuit was designed to create a frequency generator that consists of 7 steps during the operation. Crystal Oscillator – an electronic circuit made of one or more crystals or quartz located in the ...
