Unhindered electron flows clear the way for improved communications and intelligence applications. High-temperature superconducting materials discovered only 15 years ago now are enabling signal ...

Ceramic resonators offer an attractive alternative to quartz crystals for stabilizing oscillation frequencies in many ...

Researchers have developed a new chip-sized microwave photonic filter to separate communication signals from noise and suppress unwanted interference across the full radio frequency spectrum. The ...

It appears that no particular approximate [nonlinear] filter is consistently better than any other, though . . . any nonlinear filter is better than a strictly linear one. 1 The Kalman filter is a ...

Editor’s note: In this Design Idea (DI), contributor Bonicatto designs a digital filter system (DFS). This is a benchtop filtering system that can apply various filter types to an incoming signal. The ...

WEST LAFAYETTE, Ind. - Researchers are developing a new class of tiny mechanical devices containing vibrating, hair-thin structures that could be used to filter electronic signals in cell phones and ...

When you are waiting with a friend to cross a busy intersection, car engines running, horns honking and the city humming all around you, your brain is busy processing all those sounds. Somehow, though ...

In What’s the Difference Between Vibration Sensors, we focused on the advantages and drawbacks of various types of vibration sensors on the market. In signal conditioning and tips, we address the ...
