MWO: Optimization with Lists of Component Values

Hello

I'm nearly going postal :D ...
At the moment I'm trying to design a lowpassfilter but due to sharp requirements it always fails when it comes to real component values.
(That's why simple optimization won't help anything...)

So I want to try now something else: to optimize but only with real values!
As far as I know it works somehow like that:


Entering e.g. the following list of component values in the schematic
Cv={0,0.2,0.3,0.5,0.8,1,1.2,1.5,1.8,2.2,2.7,3.3,3. 9,4.7,5.6,6.8,8.2,10,12,15,18,22,27}

Then to index the values: Ck=Cv[17]
and to enter Ck where usually stands the component value.


My question is - I surely have to write it every time again for each component, do I?
And do I just have to check the "Optimize"-Box of Ck, ... in the Optimization-Value-Menu?
Where do I find which Values were chosen?


I really hope someone of you got experience with that topic :)
(Or know how to design a filter with nearly-ideal-cutoff-behaviour ;) )



Cheers.

Hello Chironex,

Answers to your questions...

Yes, you have to write equations for each component parameter every time...

Yes, you have to enable Optimize check box to optimize this parameter discretely...

Usually it diplays same location which value from the index it is using,
say fro example Ck=Cv[17]=8.2
