Armstrong Oscillator - Solid-state Devices and Analog Circuits - Day 6, Part 8

The Armstrong oscillator is much like a Colpits or Hartley oscillator but with a transformer providing feedback.

You are a great teacher. Wish I could have had you when I was struggling through a Bell & Howell course back in the early 70's. Thanks for the info. I am degreed in Electronics Engineering Technology (retired), but the road to success was long and hard, especially with a family to support and Vietnam maladies kicking in. Thank you sir!

Absolutely phenomenal lectures, everything explained and great analogies. I love your series, thank you for your time and insight

[Marvintibbitts]

I have learned so much from this program

[rstcar]

Thanks Sir, you make complicated concepts so easy to understand. I think you’ve just explained about sustained oscillations. Hopefully you’ll do a video about natural frequencies, do they apply to oscillators or just mechanical objects??

You are the most underestimated teacher ever
Nice job

What are the pros and cons of having the tank circuit at the base vs. at the collector?
The output impedance of a transistor is rather low, so it will load the tuned circuit in the collector. Wouldn't it thus be better placed at the base?

Thank you for sharing your knowledge, I built an oscillator that appears to be the Arminstrong, but the capacitor and coil are in the collector, but I was assured that it works, but it didn't, is there such an oscillator with this configuration?Thank you for sharing your knowledge, I built an oscillator that appears to be the Arminstrong, but the capacitor and coil are in the collector, but I was assured that it works, but it didn't, is there such an oscillator with this configuration?

Can u explain how radio transmitter circuits work according to electron flow and the function of electronics components used in this circuit. ....
Thank you

[AL-knyx]

Great explanation. Can you make a video on Twin-T Oscillator and Quartz Crystal Oscillators?
