It’s not often that a single photo can tell you pretty much everything you need to know about a project, but the spectrum analyzer screenshot nearby is the perfect summary of this over-the-to… ...

I set up the Agilent 33250A for a 5-kHz sine wave and applied it to the new input. Looking at both the 33250A and the Wien-bridge outputs with an oscilloscope, I slowly dialed up the 33250A frequency ...

Step-By-Step DesignAnalysis of a Digitally Controlled Wien Bridge Oscillator By Simon Bramble, Maxim UK Applications INTRODUCTION Of all the low-frequency oscillator configurations ...

The only problem with the Wien-bridge oscillator is that below unity gain it does not function. When working for a telephone company, I had to develop a 20-Hz, high-voltage sine-wave ringer circuit.

Way back when [Ms Ellsworth] was a kid, she kept seeing the same circuit over and over again in her various op-amp books. It was a Wien bridge oscillator, a small circuit that outputs a sine wave w… ...
