Finding the transfer function of a circuit

[@mistah_paari0710]

got a question close to this...FINALLY knew how to do it now... TQVM u really made my day !!!

[@srujaniam9762]

Thanks a lot. Really helped me with my assignments

[@ILIKEBUBBLEWRAP]

If you were to remove the inductor would the process for finding the transfer function remain the same?

[@ElectricalEngineeringAuthority]

Yes. So you still need to find Vo/Vs as your transfer function. If you remove the inductor then you won't have LS there anymore.

[@pritpatel242]

nice explanation !!! But is it possible to find the values of R, L and C from the transfer function ?

[@power-max]

Not in general I don't think. Suppose you find the transfer function of a simple voltage divider with no load on the output. It should simplify down to just a constant ratio determined by the R1 and R2. You can determine the ratio of these resistors but not the absolute value of each one, as that information was lost.

[@alreemjaber4286]

hello, the K in the voltage source stands for what? is it a constant or kilo?

[@ElectricalEngineeringAuthority]

It is a constant

[@mfan981]

@@ElectricalEngineeringAuthority Looking at this from the perspective of a filter circuit the K term would also be the gain at 0 frequency or DC gain correct? This could be seen as a passive 2nd order low pass filter circuit

[@ElectricalEngineeringAuthority]

mfan981 Yes it is correct

[@deep080]

What is name of the software you are using?

[@Cutebiko99]

one note i guess

[@imissmycatsm]

Why did you equate in into (Vo-KV(s))/2+s insteaf of zero?

[@imissmycatsm]

I thought it must be like this (Vo-KV(s)/2+s) + (Vo/4) + (Vo/10/s) = 0 then (Vo-KV(s)/2+s) = -(Vo/4) - (Vo/10/s)

[@imissmycatsm]

Isn't?

[@kirbyrainer7466]

@@imissmycatsm I believe it depends on what direction you draw the currents entering the node. She drew one current entering the node and 2 currents leaving the node.

What K stand for at Kvs

[@sakuranooka]

Thank you for the video. Now, once I have the transfer function, what do I do with it?

[@power-max]

You can LOOK at it. 👀

Very good. Thank you.

Fantastic!

[@Inkieto92]

question, what app did you use for those drawings and was it on an ipad or another tablet?

[@YouKnowMeDuh]

Looks like the Shetchbook app from Autodesk.

[@Inkieto92]

@@YouKnowMeDuh what about to record her screen?

[@KevinBuehling]

@@Inkieto92 Its Microsoft OneNote which is available for tablet/iPad and you can use OBS to record your screen if on a laptop.

How to solve with initial conditions?

[@JohnRobenault]

What does the K mean? Why not just make it V(s)?

[@raadraad6652]

WHATS THE NAME OF THE BOOK THAT U EXPLAINING FROM PLZZZZZZZZZ!!!!!!

[@PittyDonut]

Could you combine the parallel resistors and then apply voltage divider rule to find H(s) as well?

[@purplegk6]

SizeableVermin I did that. But ended up with a different answer.. 4K/6+s

[@Jnglfvr]

The resistors are not in parallel. But you can combine the 4 ohm resistor with the parallel s/10 capacitor and do voltage division and get exactly the same answer. Simplify the following: H(s) = K*(40/(4*s + 10)/(40/(4*s +10) + 2 + s))

super

[@johannesmphaka7433]

Why do we have to find transfer function, why is it important

[@N00B283]

So that you can bodeplot your frequencies

[@chanakyasinha8046]

Thanks 💕

[@fetch9143]

Thank you

[@spanishsplinters]

for the Vo multiple should the denominator not be 40(2+s) instead of 20(2+s) great video tho

[@ElectricalEngineeringAuthority]

So I have taken the common denominator between 4, 10, and s+2 which is 20(s+2). I hope it answered your question.

have you completed it bro?

Could somebody help😬? I need to find transfer function of [34*10^5 = 128806*10^3 * v'(t) + 91239 * v(t)^2 + 680*10^3 * v (t)] for inserting block in simulink and check simple control system. Be so kind, heelp 😁🙏
