If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close seriesA way of ...

As a result, remote control technologies are being widely adopted across various sectors. Among the many components used in ...

This file type includes high-resolution graphics and schematics when applicable. A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output.

This file type includes high resolution graphics and schematics. In a standard dc-dc converter, a resistor divider typically defines a fixed output voltage. However, applications like programmable ...

ABB has released the Switching Control Sentinel (SCS) device designed for high-voltage circuit breakers. Voltage and current transients generated during switching of high-voltage circuit breakers are ...

Electrical ladder drawings are still one of the common and reliable tools used to troubleshoot equipment when it fails. As with any good troubleshooting tool, one must be familiar with its basic ...

The final part of this series will start with bias servo circuits for automatic set up. The FETs pinch off or threshold voltage can vary widely for the same part number. Depending on the fabrication ...
