The basic circuit is the well-known Wien bridge oscillator where the R-C pairs are switched in and out of the feedback loop to achieve frequency range control.

The circuit has been in use for more than 60 years and is still in use. The only problem with the Wien-bridge oscillator is that below unity gain it does not function. When working for a telephone ...

It was a Wien bridge oscillator, a small circuit that outputs a sine wave with the help of a light bulb.

Of all the low-frequency oscillator configurations, the Wien Bridge has to be the friendliest and easiest to get along with. Like a faithful dog, it behaves itself regardless of the weather, is ...

I can remember a colleague working for weeks on a sinewave generator board for a piece of test equipment. He came up with a Wein bridge oscillator with several refinements that had wonderfully low ...

To perform this test at a reasonable cost and without letting complexity get out of control, you will want to construct the oscillator yourself and verify that the circuit you’ve built is generating a ...

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 ...
