The need for high-frequency semiconductor devices is surging, fueled by growing demand for advanced telecommunications, faster sensors, and increasingly autonomous vehicles. The advent of ...

Sounds that are lower pitched are less studied than other types. Some say it’s a health hazard. Others have doubts. By Lourdes Medrano/Undark Published Apr 17, 2024 8:00 AM EDT This article was ...

When failure is not an option, high reliability EMI filters deliver superior high-frequency EMI suppression for ...

A special technique produces very wide loop BWs in high-frequency PLLs (and hence, indirect (PLL) synthesizers), thereby achieving very low phase noise rivaling that of direct (MMD) synthesizers. A ...

Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

Our hearing picks up a limited range of sounds, limits that were used successfully to keep teenagers from congregating outside British grocery stores by a device called the “teenage sound repeller." ...

While academic research shows high-pitched sounds in general can negatively affect pets, no studies exist that determine if, or to what extent, smart plugs specifically cause such problems. A ...

This is Part 1 of a three-part series. As modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher performance than ever before, they’re ...
