Portland, Ore. — Researchers at Cornell University have created the world's smallest mechanical oscillator that is capable of being tuned electrically. The nanoelectromechanical system (NEMS), which ...
IN this method the frequency of a radio-frequency oscillator is modulated by a sinusoidal audio-frequency voltage, and the resultant radio-frequency voltage is applied to a transmitting quartz ...
If there’s one thing that amateur radio operators are passionate about, it’s the search for the perfect sine wave. Oscillators without any harmonics are an important part of spectrum hygiene, and ...
Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a ...
