This simple circuit provides better than 1% accuracy in optically coupling a DC voltage signal. To compensate for the non-linearity of the optical isolator, an identical device is connected in the ...

For electronics engineers, the real world can be a messy, noisy and dangerous place to operate. Cell phones don't work as well when they are dropped in the toilet. Laptop computers can break down if ...

These days many more audio-visual devices in the home are connected together. This is especially the case with the TV, which may be connected to a DVD player, a hard disk recorder, a surround-sound ...

Gree Electric Appliances Inc of Zhuhai has been granted a patent for an isolation circuit system and signal isolation method. The system includes a power management unit, digital logic circuit, and ...

Members can download this article in PDF format. Capacitive, optical, and inductive isolation technologies are design principles that have been around since the beginning of modern electronics. While ...

The circuit shown in the figure can monitor resistance in a noisy or otherwise hostile environment. A 1:1 transformer provides isolation and a good common-mode rejection ratio (CMRR). The resistance ...
