Accurately measuring output noise and ripple requires a basic understanding of the high frequency nature of noise. Very often, “noise” (as commonly measured) is actually the vector sum of common- and ...

Researchers have devised a revolutionary new technique for measuring the microscopic elasticity of materials. Known as SRAS, the technology works by measuring the speed of sound across the material's ...

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 ...

Modern digital receiver/exciters (DREX) used in radar and communications systems are capable of significant self-testing in a production factory environment. Long past are the days where the analog ...

Last week, I posted part 1 of a 3 part series on how to test your power supply design: Testing power supply: measuring efficiency. I covered the fundamentals about testing, including the necessary ...

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 ...

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 ...

OSHA has designated this week as “Safe + Sound Week,” so it’s a good time to think about preserving your employees’ hearing. Safe + Sound Week is a nationwide event to raise awareness and ...
