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 ...

Scientific studies, and news coverage about them, often declare that a study "controlled" for certain variables. For example, The Washington Post reported on a study of GLP-1 drugs and a hormonal ...

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 ...

In programming, a variable that keeps track of the number of iterations of a process. Its value is incremented or decremented with each iteration, and it is compared to a constant or other variable to ...

Rising power costs and load increases have elevated energy monitoring and analysis on plant agendas, but consumption only becomes controllable once it is reliably measured per unit produced and ...

Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world that would "make ...
