The Wein-bridge oscillator is an astable multivibrator with a high-Q bandpass filter and controlled gain that produces sine waves. Vocademy - Free Vocational Education
Awesome tutorial, I have built a few of these and I use a bulb, the same way HP did ! I have typical oscillator outputs @1Khz 1v P-P a THD of around 0.005% I use it for audio work and it runs off a battery so nice convenient piece of bench equipment as good as most budget sig gens and You explained this perfectly...cheers.
For whatever, unexplainable reason, I just now (consciously) discovered you on YT. Might have seen a vid beforehand, but don't remember. Anyway, great video, subscribed! 😉
I like the way in which you introduced the subject, starting from an astable MV and making the necessary mods until getting where you intended to. It'd be great if you could indulge us with a numerical design example. Great job, thanks!!! 💪🏻
I think this may deserve its own video. Think of it like pushing a child in a swing. If you push just as the swing starts to move away from you, it keeps the swing going. That's positive feedback. If you push when the swing is coming toward you it tends to slow or stop the swing. That's negative feedback.
