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 ...
What are harmonics in RF systems? A given signal’s second harmonic is approximately twice the given signal’s fundamental frequency. Ideally, amplifiers are expected to have zero non-linearities in the ...
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 ...
Operating at millimetRE-wave frequencies introduces a set of engineering challenges that extend far beyond traditional radio frequency testing ...
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 ...
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 ...
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 ...
The author is a broadcast contract engineer who has a unique way of measuring the carrier frequency of the AM stations in his care. Making off-air frequency measurements of AM broadcast stations can ...
