In this letter to the editor, the author comments on Larry Langford’s recent article “Try This With Your AM Processing.” Comment on this or any article. Email [email protected]. Distortion in AM ...

Fiber-optic interferometric sensors have emerged as essential tools in precision measurement, utilising the interference of coherent light to detect minute displacements and variations in physical ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

Trace gas sensors are used in different fields. Light-induced thermoelastic spectroscopy (LITES) has extremely high sensitivity and offers non-contact measurement, attracting extensive research ...

An “Infinite Impedance Detector” might sound a little like something that [Zaphod Beeblebrox] would use to zip around the galaxy. It’s not, of course, but it is an interesting and useful demodulator ...

As a next-generation optical archive storage device for 8K video, we have been researching and developing holographic memory. Recent studies have focused on multi-level code instead of binary code to ...

(Nanowerk Spotlight) We have written plenty of Spotlights so far on carbon nanotubes and nanoelectronics. For instance, carbon nanotube (CNT) transistors have the potential to outperform ...

I have always had a soft spot for phase-locked loops – at least, I have since I first found out what they were. What I like about them is that they servo into the best answer for a given situation – ...
