Japanese telecommunications company NTT has developed a digital coherent signal processing circuit and optical device that can achieve a capacity of 1.2Tbit/s per wavelength for optical transmission, ...

The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement ...

Negative group delay circuits represent an innovative frontier in electronic engineering, wherein the output signal appears to precede its input. This seemingly paradoxical behaviour is achieved ...

LASER COMPONENTS now offers signal processing circuits with our range of SiTek position sensing detectors. These processing circuits are able to output a voltage of all sum and differential signals ...

Chapter 11 of this book “Digital Data Locked Loops“ is being made available as a series of design articles. The first part is available here. I have spent more than 30 years toil.ing away as a digital ...

This application note includes circuits such as fast video multiplexers for high speed video, an ultraselective bandpass filter circuit with adjustable gain and a full differential, 8-channel, 12-bit ...

This video explains how diodes function as directional components in electronic circuits. Diodes allow current to flow in ...

The authors reveal that "we have had the opportunity to investigate for the first time how this signal propagation circuit is modulated by attention, that is, to identify what depths interact with ...

The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement swapping (one of the key quantum communication protocols) using sum-frequency ...
