LC Tank - Sine Wave Generator and RLC Oscillator Core - Simply Put

- An LC tank or RLC network is the core of a family of oscillator circuits which directly generate sine waves, instead of filtering square waves into them. An LC tank on its own will oscillate for only a short time, but connected to an amplifier it becomes a continuous sine wave generator.

I like the concept of DC being a frequency of zero. It makes it much easier to understand reactance.
Great video, very useful! I haven't found anyone going into this level of detail and clarification so far and I really feel like I better understand this type of sine wave oscillator now!
Wow, something clicked for me watching this. The inclusion of R and it’s effect on the amplitude helped. Your explanation of what resistance was doing, simply attenuating the signal, not affecting the frequency and then showing the decay due to the resistance inherent in the system helped so much. The LC circuit is maintaining a frequency, it’s just fading. I’ve been an extra class ham for over 20 years now and never really fully understood an LC tank. Fast forward to my holiday break here and I am trying to create one and test it on an oscilloscope. Super helpful.
really good explanation! thank you
What a great and detailed educational video. I love the ending as well! Thank you for your efforts.
Great video!
Great explanation, as usual.
A lot like a chain-of-pearls kinetic desk toy pinging back and forth.
really looking forward to the next video!!
Thank you
I love your videos. The subject is well explained. Thank you.
So far so good ....but since wave generation ..mostly in inverters as well as in other applications are so different ..but again as a science u r perfect
Thank you thank you!!!! What an amazing explanation
The resistor can effect frequency of the circuit because controls the rate a which the inductor is charged up.
As I go over in the video, the resistor affects the flow of current linearly, meaning it is constantly dropping a percentage of the voltage (according to V=I*R) which affects the amplitude of the signal, not the frequency. A resistor dissipates power; It does not literally "slow down" the flow.
@@simplyput2796 interesting you bring that up. I used to think of resistors in terms of slowing down the current until I realized the effective "slowing" of current was merely a phenomenon caused by their primary power dissipation function. A 'current limiting' resistor in an LED circuit is actually a power dissipator which only allows a limited current to flow through it based on TEMPERATURE (and that's an important feature most people forget to mention, because the temperature of the component is the result of power dissipation over time and ambient factors).

Is it possible to add a second inductor with the opposite polarity of the first inductor to this circuit? So that during the discharge of the capacitor the inductors switch polarity in timing with each other? I am not sure I worded that properly.
good thank u
Well done
So, how do you make a negative inductor so that power amplifies instead?
Why oscillation do not continue when constant voltage is supplied???
When all components can be modeled accurately as having all three when don't they natural oscillate.
There is not just resistance but radiative loses.
well done which simulator do you use ? OK I got it :-)
Greatttttttt
Muy bueno...
So ideally and theoretically the other frequencies do not show up ever... ?
Perfect ideal components would oscillate at the one frequency and no other, but real components and circuits will have noise, and from what I've seen (since I'm still doing the learning), some of the more advanced oscillator circuits using LC tanks specifically counteract this using various tricks.
