RLC Band Stop Filters and Band Pass Filters

This electronics video tutorial provides a basic introduction into RLC Band Stop Filters and RLC Band Pass Filters. An RLC Band Pass Filter blocks high level and low level frequencies while allowing mid level frequencies within a certain range to pass through. The RLC Band Stop works in reverse. It blocks mid level frequencies allowing high level and low level frequencies to pass through the circuit.

You sir, are a champion. You have a way of teaching that few possess. Thank you for making these videos!

[@grahamstreet6537]

I am very impressed. I was looking for a straighforward explanation and here is your video.

[@andrewgillim5952]

Julio, you are the most amazing teacher on the internet! Thank you for all you do.

[@tanveernaeem1157]

Don't have words to admire your ability to explain rather complex concepts in an easy to understand style. I learned in these twenty videos which I could not in twenty years. Thank so very much for sharing your knowledge and keep these learning nuggets coming. ❤

If only he understood consciousness. 🧐😮‍💨

[@BASEDinMaine]

Thanks for this, I needed a visual overview of these 4 for my AC Circuits final tomorrow. One thing future travelers should note, is that when an inductor (L) and a capacitor (C) are placed in *parallel*, at the resonant frequency (XL = Xc) they actually create something approaching infinite impedance to flow, which is a sort of virtual open circuit, thus blocking the path of current. I needed to see this laid out to really get how the signal was being filtered or not.

Very well explained!!! Thank you!!!

Band pass? More like "heck yes!" Keep these wonderful videos coming!

I use these types of filters when I make music as well! Didn't know they applied to other subjects!

This stuff is ubiquitous in all area really.

Hey bro, you are an awesome teacher. Is there some formulas to design a RLC bandpass and bandstop filter just like your previous 2 videos.

[@edi_naorem]

video is great !!!!!!

[@jyotirmoysahoo1024]

Thanks sir

[@marimo11]

thank youuuuu

[@user-su5sq5ib3i]

If the rlc band pass or band stop do the same filtering both in series and parallel what is the advantage of one over the other???

[@emoide78]

Hi, thk u for this video, i can i block a frequency around 2/2,5k? Bless

[@niksa28]

Just know L and C in series only allow their resonant frequency to pass through, all other combinations can be reconstructed from that.

[@chetanwa666]

Do bandpass filters work by resonance and bandstop by anti-resonance?

[@elijahjflowers]

Does this apply to digital circuitry too? Asking for Music programmers.

[@nimeshrajakaruna1909]

if input voltage has a internal resistance ???? what to do ??? in band pass filter in series

[@successthruknowledge]

Well, I never heard of band block filters so I learned something new! I do have a question that I meant to ask a long time ago. Why do you include the terminal on the right bottom of your circuit? Cannot the mid-level frequencies flow to the output of the lower right terminal? Also - HURRAH I have watched 100 videos in your electronics lectures series! 44 more to the finish line~

[@peterkondas1685]

is there any difference in formula of resonant frequency between parallel and series RLC circuit ? can I use Fr = 1/2Pi sqrt(LC) for series circuit ?

[@edwardgatenew5125]

There is no difference brother, same formula for fr applies regardless of the type of the circuit

[@davidchukwu5171]

GOAT

[@jhosephlarosa1281]

Can you explain me the purpose of adding a resistor on this circuit, cause I wanna learn this things

[@sytiravajous]

I'm guessing it could be a potentiometer to adjust how much gets filtered out. Learning also here lol

[@markday3145]

With the series band pass and parallel band stop filters, what does the resistor across the output do? What would be different if there was no resistor?

[@BASEDinMaine]

If there was no resistor between the output, the current would have an unobstructed path to ground and the output would receive no signal (current takes the path of least resistance). The resistor allows the current to split to the load.

[@AsyncVoid]

@@BASEDinMaine You've assumed the resistor would be replaced with a short - why cant it just be open (no resistor)?

[@Mandrag0ras]

So why is the resistor needed in the Parallel RLC Band Stop Filter?

[@user-su5sq5ib3i]

Becuase it sets up a bias for one and the other is that the Xl /Xc filter needs a resistor to reference against

[@user-su5sq5ib3i]

You would have a dead short on blocking frequencies

[@kensvenzZz]

Sir tell me formula fc of Band Stop Filter... PLEASEZZZ

[@helionyanna4655]

How to find the transfer function of these filters?

[@omara.7107]

By setting up a Voltage divider equation without Vin (since the transfer function is Vout/Vin), where the output branch's impedence goes on top an total Impedence goes on the bottom

[@nikolosborne118]

Capacitor passes low frequencies, inductors pass high frequencies as far as I know. Not the other way

[@rolinychupetin]

You both are right. How is that possible? The capacitor in series lets HF signals pass, and blocks LF signals, but the capacitor in parallel with the output does the opposite, it shunts to ground the HF (which prevents them from getting to the output port destination, the load) but not the LF (which lets them pass to the load.) The impedance of the capacitor, in ohms, is inversely proportional to the frequency of the signal as per Zc = 1/(i.w.C), where i is the imaginary unit, w in rad/s, and C in farads. I hope that helps.

[@jamesbroughton2199]

Hold on, I thought it was the other way around? I thought a resistor followed by a capacitor was a low pass and a resistor followed by a inductor was high pass

[@albertschrocker9995]

Sorry, but I do not understand the behavior of the Parallel RLC. L and C are parallel. That means for me, a high fr can pass the capacitor, the low fr can pass the coil, because both components are parallel and and fe there is no need for a high fr to go through the coil.

[@Jmagic36]

instead of thinking of it as a capacitor passing high frequency while the inductor does nothing, think of it as the inductor absorbing the higher frequency, and the capacitor passes what isn't absorbed.

[@dwiastuticahyasiwi1918]

1:53-2:06, does the industor really pass the low frequency instead of high frequency because in your previous video of low pass filter, the capacitor pass the low frequency?

[@annd6546]

Btw first comment lol

[@andrewgillim5952]

Beat me to it lol

[@niksa28]

no one cares

[@wf.i.7260]

What if there is a combination of series and in parallel? No one gives such an example. The whole web can't put 1 example together. BUT my teacher asks these kinds of circuits, even without him teaching us anything that resembles it. ----- [Resistor] -----------|------ [Capacitor]------|---------------------o + | | | | Vin [Capacitor] [Resistor] Vout | | _ | | ----------------------------------------------------------------------------------o What about this circuit? According to the video, high frequencies pass through both capacitors. Do they make it to Vout? Also, the low frequencies are totally blocked. So, this is a high pass filter or a band pass filter?

[@needful3961]

So much work put in a comment that will never get answered. I'd do it myself, but I have no idea.

[@simozy4475]

what's the purpose of such circuit anyway, it just doesn't make sense to put a capacitor in parallel followed with another one in series especially when we're talking about filters

[@wf.i.7260]

@@simozy4475 I don't remember asking for meaning behind the circuit. It was in an exam and it seems likr no one's able to solve it. End of story. Fk that teacher. We moved on.
