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 ...

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 ...

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.

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 ...

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

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 ...

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 ...
