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 ...

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 ...

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 ...

A Pie control can analyze one, two, or three independent variables. The number of data dimensions must correspond to the number of independent variables in the analysis. To set the data dimension, use ...

The goal of controlling a system is to reach or retain stability. In control theory, stability is described with the Lyapunov stability criteria and mathematical models that set into relation the ...

To make color a response variable in the graph, you can specify a numeric variable whose values are indexed into the defined color range to determine the colors to use in the graph. To assign the ...
