Spoiler summary: The quarter-wave stub resonant frequency, when built in FR4, is about: f[GHz] = 1.5/Len[inches] or f[GHz] = 3.8/Len[cm]. Remember: before you start using rules of thumb, be sure to ...

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 very fabric of the universe is ringing with gravitational waves from its earliest epoch, and researchers have finally "heard" this cosmic symphony. On Thursday, June 28, the North American ...

New methods of detecting ultra-low frequency gravitational waves can be combined with other, less sensitive measurements to deliver fresh insights into the early development of our universe, according ...

In a historic first, astronomers have detected low-frequency gravitational waves using a galaxy-sized antenna of millisecond pulsars in the Milky Way. When you purchase through links on our site, we ...

A new study has found high frequency propagating activity patterns in the motor cortex that contain details of upcoming movement -- information that could lead to the development of better ...
