We are always impressed with something so simple can actually be so complex. For example, what would you think goes into an analog computer? Of course, a “real” analog computer has opamps that can do ...

Vol. 95, No. 1/2, The Contributions of Logic to the Foundations of Physics (June/July 2010), pp. 279-300 (22 pages) Earlier, we have studied computations possible by physical systems and by algorithms ...

Some ideal operational amplifier (often op-amp or opamp) configurations assume that the feedback resistors exhibit perfect matching. In practice, resistor nonidealities can affect various circuit ...

Sometimes the simplest hacks can be the most useful or ingenious, and such is the case with [Keri Szafir]’s method of ensuring that potentiometers used in audio devices are matched. If you consider a ...

Many conventional strain gages are similar in appearance to Figure 1. A serpentine pattern etched into a metal foil creates a relatively high resistance in a small space. The foil is bonded to a thin ...

Viatran develops pressure transmitters with four different pressure sensing technologies. The company analyzes the requirements of an application and selects the technology that ideally serves that ...

The first customer in Canada to use a Wheatstone Generation/Bridge system will be Metro Radio, the Halifax division of CHUM Limited and Newcap Broadcasting Ltd. The user ordered a Wheatstone Bridge ...

WERS(FM) at Emerson College in Boston is expanding its Bridge Routing System to equip two studios with Wheatstone control surfaces. The station already has 11 Bridge Router frames; it chose G and E ...
