passive analogue circuit in digital representation

[DigiTonix]

I understand you so . -

YOU DO NOT WANT
1) use imitation impulse.
2) simulate the final result.
3) in every way imitate, simulate components.

DO YOU WANT TO

1) Make a real equivalent of the filter.
2) Use calculation functions for the circuit
3) be able to solve any scheme.

My conclusion.
As far as I understand.
You can do this in Flow itself. Without using other tools.

You need to download MARSHALL TONESTACK.osm
I think it will be useful for you.

You are not looking for easy ways! I support your initiative!

Also Matlab will definitely be useful! You talked about him in the first massige...
I have not seen any other solutions.

I think we can make a tonestack calculator.
Which works for different circuits,
I think this is a great idea for everyone.I used

I think you can do this for all types of schemes.

All my suggestions, I maximally compared with your question.

I am researching this method of Tone stacking. It's quite complicated. I was doing some research and the alternative;
In contrast is labeled simplistic. Surprised Me . Do You know if that file is available somewhere here on the forum?
I was looking at naint.com and that link was not operating (the 75% close one).

Maybe I have it, I can not find it, if I find it I will send it here)

Hi There.

If what you need is a electronic schematic to flowstone dsp converter. Unfortunately it does not exists.

But, wave digital filters are indeed a very good solution if you wan't to emulate an electronic schematic without writing equations. The main idea behind - propagating waves with matched impedances at junctions - keep the computational complexity low in the sense there is no need for a global solving of every node (component).

I remember reading about a tool capable to go to implémentation from a SPICE netlist, can't remember where I read that...

These method are great but does not allow multiple non-linearities in the schematic without big computational loads. You can easily end up writing multidimensionnel solvers... that's not fun.

But as long as you keep doing linear things it's all good ! The drawback is I don't know any way to do this in flowstone as it is a processing propagating all down to a tree coming back.

Maybe later KG_is_back experiments on callofuhulu function could help...

What you can do is write down the nodal ODEs and solve with some scheme, Euler being the simplest. Like here:

Works as long as you stay away from the Nyquist frequency

Yes Martin. KCL is relatively easy.
I recently found this really useful

I'm completely confused...

But I think that using convolution, together with filters gives the best results ...

If Multisim could be working in real time, it would be great!
