This is part one of my series on electronic oscillators. In this video, we explore the fundamentals of electronic oscillators. What is oscillation? What kind of things oscillate? What are oscillators? We explore pendulums, acoustic feedback, and the phase shift oscillator.

In just the first 15 minutes of this video, I gained more knowledge than I did throughout three years of high school physics. Thanks a lot Bob, I'll definitely be joining your Patreon!

Super stuff Chief! Please do a vid on why mixers use multiple 22uF caps between every stage on the channel - ie Input-Gain - Treb-Mid-Bass- Eff-Pan-Vol out. Literally stacks of them - with no combined effect on the final EQ. (perhaps)? But normal pre-amps don't have these dudes all over them!

Thank you so much! These videos are so useful!

Great explanation!. The filter at the output is a parallel LC filter. If it is tuned to the frequency of the oscillator it will block the output of the oscillator. A series LC filter should be used.

My question is, why the pendulum perpetuum mobile with two strong magnets at the two high points is not possible? The magnets would put energy back into the system, and give the necessary push for the pendulum to reach the other magnet at the opposite high side. Why this is not working in practice?

I've learned so much from you Bob. I've been able to use the things I've learned from your videos at work! As a side note, could you do a video on the terminology I see a lot of? For example, what is the difference between signal vs reference voltage, common vs ground, etc? Also maybe some videos on how to build and, or and not gates.

Amazing video as usual! I watch every video and study the course on the website, thank you Bob!

This is a really nice and clear explanation of oscillators, @ 22:34 , I see how feedback can be used to keep the oscillations going when it’s needed, but whats a resonator?? Thanks Bob.

@Vocademy-Electronics-Tech 4 месяца назад

If you look that up you will find that a resonator is, "A resonating system." I think you can define a resonator as something that oscillates; to resonate is to oscillate. A resonator can be a pendulum, a bowl of jello, a musical instrument string, an organ pipe, etc. Here's the Wikipedia article if you want to dig deeper: en.wikipedia.org/wiki/Resonator

very nice....one thing missing for me is to complete mathematical formulas and calculations for designing these circuits.

@MensahJ 4 месяца назад

I just used one in an AM transmitter. 😁

@Msmsm184 4 месяца назад

Hello, Very very good explanation. Sir, Could u pls make a video on smps (switch mode power supply) from A to z in one video also with safety components. And when will u upload this video?

Focault does not prove the orbital motion ... but great videos!

@Vocademy-Electronics-Tech 4 месяца назад

I didn't say that. I said it proves the rotation of the Earth. By the way, to rotate means to spin on an axis. To go around something, as in an orbit, is to revolve. We amateur astronomers have to correct people on that all the time. Here's a good video that explains how Leon Foucault predicted his pendulum's motion at different latitudes and how hundreds of pendulums around the world agree with his predictions: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8JxyT0edT6c.htmlsi=UUsGd-5IVpmuUBj3

@martf1061 Месяц назад

@@Vocademy-Electronics-Tech but you know that when foucault presented his pendulum to the science commitee, he never thought that they would believe and be convinced... ( a pendulum that swings indefinitly and is also attached to the ceilling of a building, and this building is solidly anchored to the surface of the planet...) The pendulum was put in motion, and kept in motion by someone or something. And that someone or something made it swing slightly and subtily to the side... The only way this demonstration can work, would be to have the pendulum attached to something that is Not touching the surface of the planet.
