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 ...

I’ve now discussed the basics of the frequency folding tool from Analog Devices in two previous blog posts this year, Analog Devices Design Tools: ADISimADC Frequency Folding Tool and Analog Devices ...

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 ...

How do you ensure that every part of a system receives the clock it needs—without wasting power or sacrificing performance? The answer lies in creating a well-structured frequency plan built around a ...
