Although GRC (the GNU Radio Companion) uses the word radio, it is really a graphical tool for building DSP applications. In the last post, I showed you how you could experiment with it just by using a ...

While designing an internet of things (IoT) project that also required a long radio-frequency link, it occurred to me that there are pre-wired modules already built to do that. In fact, not only do ...

How do you know that your patch cables are good? For simple jumper wires, a multimeter is about all you need to know for sure. But things can get weird in the RF world, in which case you might want to ...

Radio-frequency (RF) control of an ultrasonic phononic crystal was achieved by encapsulating it in a composite of high k-10% KF-doped BaTiO 3 dielectric nanoparticles with poly(N-isopropylacrylamide) ...

A Rydberg receiver and spectrum analyzer detects a wide range of real-world radio frequency signals above a microwave circuit including AM radio, FM radio, Wi-Fi and Bluetooth.A new quantum sensor can ...

Here’s What to Remember: The Reaper technology, identified as the Reaper Defense Electronic Support System (RDESS), is described as having successfully tested an anti-jam, anti-spoofing application ...

It's almost impossible to think about modern IT and networking without bringing radio frequency energy (RF) into the picture. That means it's equally impossible to fully consider IT security without ...

Abstract: Accurate weather forecasts are crucial to ensure that the nation is responsive and prepared for weather and climate disasters. Passive microwave radiometer measurements of temperature, ...
