A simple tweak to the usual setup is all that is needed to enhance a spectroscopy technique that uses waves in the terahertz ...

but understanding the electronics behind modulation and demodulation of an FM signal can be confusing. We’ve covered the basics before, but FM is so tightly associated with broadcast radio ...

Utilize analog and digital signal processing techniques in building a low-cost high-precision digital oscilloscope for high ...

Plasmonic modulators are tiny components that convert electrical signals into optical signals in order to transport them through optical fibers. A modulator of this kind had never managed to transmit ...

Current super-resolution microscopes reveal structural details but lack chemical specificity. To overcome this limitation, researchers developed structured illumination mid-infrared photothermal ...
