In need of a "transfer function"

Postby wlangfor@uoguelph.ca » Wed Nov 21, 2018 3:03 pm

Ok, so by now I have many many schematics to study.

And I thought sillily the other day "transfer function, hmm - I must have that somewhere..." and after three hours of looking started to work on another project. Interestingly it's the new EQ Gain plot; An adaptation I made for the Flowstone Stock EQ V2.

But yeah, can someone share with Me their "transfer function"? I thought it would be in an older version; Tried to find it that way, maybe I missed it....?

Thanks.

Umm, there is no single transfer function, its a general term to say how a function changes the input. What are you looking for specifically?

I want to test My Equalizer so as to make it work correctly. It's the one like Martin uses with a plot and decibels with frequency. Thanks Adam.

BTW, I was able to get the EQ to 1% CPU, but I wasn't happy with just ZDF Filters. I'm rebuilding it from scratch. It'd go well into a synth (when I make the small version).

Here is what I use for filter analysis. The demo includes a set of standard filter types implemented in ZDF topology.

Thanks Martin, now I'll get the EQ up to par. :)
