well..if it's easy to port it to SPICE then you have the advantage that

 

if you want to make a board, the schematic is already in EAGLE. that

unfortunately, i believe that the best way to get learn about the freq

 

domain is to study it. use old books (like from the 60's) that don't

rely on computers and DSP. learn how to use the s-plane. someday I will

 

have time to do this properly, too

Thanks Gary. I think I agree. It makes sense to do the capture in Eagle,

then port to B2 Spice. I will be doing less simulation that schematic

capture so I think it's more efficient this way.

For what it's worth, when I started getting back into electronics a year or

so ago, I bought some new tools and I do have a good (not top of the line)

dual trace scope with FFT.

For context, my background includes graduate degrees in physics and

bioengineering, and I took several EE courses as a senior in undergraduate

school. I've done a lot of control system design and analysis so the "S"

plane is (well, used to be) my friend :). I've designed and built

instrumentation/data acquisition systems, and for the past several years,

I've been analyzing dynamical systems and writing some dynamic simulation

code. That said, I never did really learn analog design. I'm still

convinced it's done in dark rooms with chicken bones and black magic

The modules are mostly pretty simple. A few op-amps, a couple of

transistors, and the requisite capacitors and resistors. Even the most

complicated ones typically fit with room to spare on a 160 X 100 mm board.

So far, none are my own design and so their respective designers have done

the breadboarding and confirmed their designs. There are just so many I'd

like to look at and learn from but I'm disinclined to buy the parts and

spend the time breadboarding them. I'm hoping I'll be able to get enough

out of a decent simulation to satisfy my curiosity.

I do appreciate the time you've taken to discuss this with me.
