Ok. Thanks again.

No. Thank you for your time. It is very much appreciated. Can't say that enough!

Yes, that is true.

Cheers. I'll take a look at that later on!

As long as one understands the problem I imagine. Still to get to 4/5th order systems and that's where that I'm hoping this packages will pay off for!!

Yes, of course. I don't learning something new. It keeps the brain fresh :)

I'm sure that you're right and I believe so too!!

Well, it better :) otherwise, I'd be back for a bit of more assistance. Fingers crossed that it doesn't cometo that!!

Thanks

Ok. Will do.

Okey dokey. I'll make it my task for this morning to get it all resolved and I'll let you know how I get along. Wish me luck!!

Me too. My confusion right now is whether I need to uninstall the Cygwin first, before I try to instal Sympy and Sagemath or not!!

Yes, I'm sure it will be and that's why I plan to sort it out ASAP.

That is, how to install and uninstall the packages!

To be honest with you, it's been so long that I've all but forgotten how to do it. But, it shouldn't take me too long to figure it out again... I hope!

Ok. Looks like I've got a bit of digging and refreshing to do.

That's certainly what I'm hoping for. I'd also like to get a handle on the way that you present your circuits for analysis!!

Sorry, before you go ... do you know how to check what Python package I have without me having to look for my notes from 3 years ago?

Thanks :)

Yeah, that's what I'm actually hoping for. Something to make my analysis a lot easier!

Thank you very much. Your assistance is very much appreciated.

Ok. I'll give them a try or atleast see if I can install themwithout any hiccups and I'll let you know how I get on. Thanks again for the heads up!!

Ok, I never knew that. I'll give the Windows 10 installer a try then.

I think that I'll probably go the Sagemath way to make it easier!

Oh and by the way, I am using Windows 7!

Hahaha. That's what I started on and I'm familiar with :)

So, I may have yo refer to Sagemath after all. Although, I would prefer not to, if it'snot required!!

So, I'd loaded Cygwin Terminal which is what I was previously using to write my python scripts. But, I feel like a fish out of water because I've not done any python programming for over 3 years!

So, do I also need the Sagemath program too?

Ok. i'm not familair with those two installers. But, let me just check to see what Python package, I currently have.

Yes, like I was just saying. It can be kind of tricky installing Python packages, if my memory serves me right!!

It's been a while, since I last used Python, so I may need a bit of hand in installing it. But, I'll let you know if I come across any issues!

Thanks for the link.

Ok, it seems that is Sympy a part of Python!

Ok. I've just googled it. It says that it builds on top of existing Python packages.

Ok. Is Sagemath a Python package?

Hi, thanks for replying and so quickly too.

@jonk Ok, will do. I'm not familiar with any of those packages. But, I'll certainly let you know once I've got and installed them :)

@jonk Hahaha, that was exactly what I was hoping to ask you. But, I've resigned myself to going with the one method that I know for these types of circuits for now and will revert back to your method as my understanding improves! Or I may just grab a copy of Sympy, in the meantime :)

@jonk Sorry about that. I removed the extra bits that I had included because (1) it was getting a little messy with the algebra and I didn't want to spend more time dealing with another question based off one that had just been answered and (2) I wan't sure if it would be frowned upon that I was asking a follow up question in one that had already been answered. But, thanks for getting bck to me!

@jonk I've just edited my post to pose a question regarding your steps and was hoping for a quick assist. :)

Wow and all of that without a university/college course. People were certainly a lot more smarter back in your days! But, all of that gives me hope.

That's exactly how I feel taking this path and I feel that it will be a worthwhile journey to take for those exact reasons. However, would you say that it's a smart move to take on board analog and digital design and embedded programming all at the same time? :)

@jonk I'm glad to hear that. So, there's hope for me yet :)

No. Not for me :) When I initially started this post, I was nowhere near the final transfer function that I had. It was whilst writing this question that some things became clearer to me and I was able to arrive at the transfer function that I did. I put this all down to not having had a formal education in electrical engineering and trying to teach myself!

I've just noticed your new addition to your answer. Basically, I'm looking to go from your new answer, I/Vin to your previous answer of H(s) and looking at your two answers, the only difference in their expressions is that the numerator for Vout/Vin TF is multiplied by Zc=Z2, which was what I was trying to clarify, i.e., whether multiplying I2 by Zc would give me Vout and reduce the numerator term from s^2*L*C to s^2; which it does, looking at your two answers! So, thanks again. Iknow that it has taken a while, but we got there in the end :)

Yes, indeed. You've gone into a lot more detail, in particular, with how to get it to the canonical form, which will come in useful for me. Basically, I'm trying to achieve the final form shown at the beginning. But, using KVL, I get a TF with I2(s)/V1(s), which isn't what I want, but Vo(s)/V1(s) and I was wondering if what I suggested in my comment was the way to get there!

@aconcernedcitizen did something similar yesterday for my initial question using the complex impedance method. However, I wasn't able to follow it the way that it was laid out, but I think that I might be able to follow your example; which is something that I will do in due course. However, would you say that I am on the right direction, regarding my comment?
