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 ...

If you’ve ever worked with guitar pedals or analog audio gear, you’ve probably realized the value of a resistor decade box. They substitute for a resistor in a circuit and let you quickly flick ...

What kinds of applications utilize precision resistor trimming? Obvious applications include setting operational-amplifier gain and offset and voltage regulator output (Fig. 1a and 1b). But there are ...
