Interference from electronics and AM radio signals can disrupt the internal magnetic compasses of migratory birds, researchers report today in Nature. The work raises the possibility that cities have ...

Key takeawaysThe noise that disrupts communication devices and sensors results from electrons being scattered by defects and ...

Electromagnetic interference is becoming a bigger disturbance in power electronics and other systems. Explore the many different types of EMI filters that can cut through the ...

Pulse Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This method ...

Consumers want things to go faster, be it cars, microwave dinners, lines at the grocery store or Web connections. But the cost of speed in electronics is often "noise." That noise causes interference ...

Active noise cancellation (ANC) is a system or technique of applying an anti-noise waveform, which closely matches the shape and frequency of the offending noise waveform, at an angle of precisely 180 ...

Photonic chips process and transmit information using light instead of electricity, guiding photons through microscopic structures on a chip.
