Abstract: In this paper, thorough analysis along with mathematical derivations of the matched filter for a voltmeter used in electrical impedance tomography systems are presented. The effect of the ...

If you work on simple digital projects, just about any bench supply will offer the voltage and current you’re looking for. However, if you’re working with valves, you’ll often find yourself needing ...

Electronic paper or ePaper is a display technology that exhibits the appearance of traditional paper. E Ink is a specific brand of ePaper technology, and it has been deployed in various products that ...

The purpose of the on-chip LDO is to provide some extra PSRR for the (semi-sensitive) analog ADC frontend. Do extra research to see what specs can be achieved, but essentially we need an OTA that has: ...

Check out this interesting wideband AC millivoltmeter circuit from 1990. The simple design features 12 ranges, decent accuracy, 200 µV accuracy, and a frequency range from 20 Hz to more than 2 MHz.

When I first thought about making a voltmeter, I wanted something small, easy to carry, and quick to use. I imagined it as a tool I could keep in my toolbox or use as part of a quick diagnostic kit.

Many basic function generators cannot measure output frequency or amplitude. This module addresses that by displaying both on a two-line LCD. It also functions as a standalone true RMS voltmeter with ...

At the time of writing, some colleagues are working on a demonstration for the big “Embedded World” show in Germany. They’ve plumbed in some natty speech-recognition technology into our super new dual ...
