I recently had a discussion about measuring noise density (i.e., op amp noise) with a digital oscilloscope. While we certainly use oscilloscopes to measure time domain noise, as can be seen on nearly ...

Why You Can’t Just Use a Spectrum Analyzer Industry has an increasing demand for spectrally pure signals in applications such as imaging radar, mobile communications, satellite communications, weather ...

Three tools are typically used to measure vibrational noise (noise) - a storage Oscilloscope (scope); a vibration sensor (sensor), which is generally a 'seismic grade' accelerometer 1; and a ...

Nuclear physicists proposed a method to measure the speed of sound characterizing matter created in nuclear collisions. Heavy nuclei consist of hundreds of protons and neutrons (belonging to a group ...

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 ...

Designing total-harmonic-distortion (THD) measurement into a system usually involves a notch filter and a broadband ac measurement. The problem with this technique is that it measures both THD and ...

Martian landers have been able capture measurements of wind speeds -- some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image 'tell-tales' that blow ...
