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 ...

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 ...

A signal unlike any other has reached Earth. Detected by the 3I/ATLAS project, this unique transmission wasn't random ...

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 ...

In August 1977, the Ohio State University Radio Observatory picked up a radio transmission from the Sagittarius constellation that was so strong it inspired the astronomer who discovered it to write ...

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 ...
