Optical signal transmission can be significantly improved by limiting the wavelength of transmitted signals. Fiber Bragg grating (FBG) is a technique widely used in optical communication, sensing, 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 ...

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 for other more exotic ...

Kalman filtering has long served as a foundational tool for state estimation in dynamic systems, offering a robust and efficient means of filtering noise from measured signals. In the realm of ...

WASHINGTON — 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 ...

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 ...

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 ...
