Let's build and test a Wien-Bridge oscillator (3 - Oscillators)

Benchtop build and test of a Wien-Bridge audio oscillators. Let's look at all the key features of the waveform on the oscilloscope and how various circuit components affect them.

Excellent lecture. Perfect combination of theory, math, and demonstration of the real circuit, makes it a lot more interesting and easy for students to comprehend.
You have a very clear voice, and good time allocation too.
Thank you for putting your video up on TH-cam.

This was great. I hope you do more videos like this one. Showing the information about the oscilloscope was very helpful.

Спасибо! 33 Ома, определенно, лучше, чем 22! 🥳👍

Thank you for sharing / making this video. When you say adding a "Buffer" to prevent loading of the oscillator, do you mean adding another Wien bridge circuit on the frequency output so the first oscillator does not get loaded or just adding a capacitor would do the trick? (in series with the output pin?)

[@adanner]

A capacitor won't do the job too well; another amplifier with a high input impedance will work well as a buffer. I have a video on buffers which might be helpful:
