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 ...

Radio frequency (RF) was once a noninvasive treatment you could only access in-clinic, but thanks to advancements in technology, it’s now available for home use. So how does it work exactly? RF uses ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

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 ...
