Trimmer potentiometers are ubiquitous components and are available in a variety of packages, resolutions, and temperature stabilities. However, none of these potentiometers implements anything but the ...

Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

The circuit shown is a differential amplifier that not only offers programmability but also provides a logarithmic-type gain (Fig. 1). The traditional gain-setting resistors of the amplifier, R1 and ...

Winbond Electronics, based in HsinChu, Taiwan, is a relatively new supplier to the digital potentiometer market. Their first offering, the WMS720x ICs, are “set and lock” devices targeted at ...

Given a nonempty compact connected subset $X\subset {\Bbb S}^{2}$ with complement a simply-connected open subset $\Omega \subset {\Bbb S}^{2}$, let Dome(Ω) be the ...
