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 ...

The figure shows a schematic for an oscillator amplitude-control servo system. The circuit creates a closed-loop system that supplies a fixed and adjustable peak-to-peak amplitude ac signal centered ...

You have just spent $10,000 and put in hundreds of hours to build the latest true turbojet powered radio controlled scale model of an F104 Star Fighter, a model that weighs 30 pounds and that will fly ...

IN the course of an investigation into servo circuits and self-balancing systems in general I had opportunity to examine the effect of reactive elements in the negative feedback networks of electronic ...
