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 ...

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 ...

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 ...

Hardware-design engineers have long recognized the usefulness of RC lowpass filters (Figure 1). Lowpass filters are useful for performing signal conditioning, removing noise from a signal, or ...

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 ...
