Here is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are similar circuits in the literature [References 1, 2, 3] which require ...

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 ...

Agilent Technologies Inc. today announced that its PXA signal analyzer is now the industry’s highest performance millimeter-wave signal analyzer, covering frequencies up to 50 GHz. With external ...

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 ...

It is known that the human body can generate mechanical vibrations at very low frequencies, so-called infrasonic waves. Such low-frequency vibrations are produced by physiological processes—heartbeats ...

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 ...
