When something is described as “Low Noise”, it is by the nature of the language a relative phrase. The higest quality magnetic tape is low noise compared to its cheaper sibling for example, but still ...

Noise is all around us, and while acoustic noise is easy to spot using our ears, electronic noise is far harder to quantify even with the right instruments. A spectrum analyzer is the most convenient ...

Lock-in amplifiers let you measure very small signals that would otherwise get lost in the noise of even the best available amplifiers. Originally analog circuits, lock-in amplifiers have evolved into ...

Analog Devices, Inc. (ADI) introduced today the industry’s lowest-noise, zero-drift operational amplifier. The ADA4528 zero-drift op amp is designed for instrumentation and medical applications that ...

Piezoceramic (PZT), or "piezo," actuators are known to be excellent position transducers in the nanometer or micrometer range. These actuators are widely used in many precision applications. PZTs, ...

This file type includes high-resolution graphics and schematics when applicable. The biggest problem with precision noise measurement is that the noise floor you’re trying to evaluate is frequently ...
