Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

This application note describes a closed loop, computer- controlled, variable attenuator for the control of output power from a tunable laser. It is based on the combination of a 1/2 wave-plate and a ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

Soft starters and VFDs both effectively control motors and are efficient users of energy. Determining which technology to use depends on understanding the performance needs of the application. A ...

Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

What is the purpose of prescribed practical P4? To investigate experimentally the relationship between the mass and volume of liquids and regular solids, and analyse and interpret the data gathered.
