Quote: Any schematic I have for EQ uses capacitors and inductive coils, in conjunction with resistors.  I can't find a single resistor only EQ.  My understanding is that they work through frequency dependent phase shift, but not resistor induced current delay, if that is even possible. A single resistor doesn't induce any delay (at least in the MHz range), but here's one very obscure filter that doesn't use any external capacitors or inductors.    http://m.bareille.free.fr/modular1/vcf_polivoks/vcf_polivoks .htm I believe it's the only example of such a design I've seen. Another "why would you do that" kind of a thing.

But you have two active components in this.  It's not resistor only.

BTW, Jeff ... I never said he didn't deserve his client list.  Also, me threatening to show you "widening where the sun don't shine" is obviously hyperbole, for comedic effect.  That anybody would think that I would physically threaten somebody, is ludicrous.  I play hockey every week with a guy who distorted a record of mine, and I've never once made him pay for it, even on the ice!

But no caps or inductors; it's a weird circuit.

Don't poison my sushi tonight.

i needed to attend to some family business in august... not play hockey,
(or futz with my website). so how was the sushi?

and what probably has a tiny bit of crosstalk?

like it or not, a lot of analog gear performs that "stereo technique".

Hey, it's this topic again. It inspired me to apply reverb on everything, but only after doing some parallel multiband M/S upward expansion. It just doesn't work the other way!

So something good did come from the thread, after all.

so the sushi was just ok then?  some say it's best to eat raw fish
during months with an "r" ... i hope that no one got ill.

I think the sushi place was closed that night and we had Thai instead.

I've never gotten ill from sushi.  Only from cooked food.

Indeed... This filter relies on current starving a programmable power opamp and thereby manipulating the GBP of the amplifier.

I'm a bit late to this thread and It's now quite fragmented, but I'l try to answer and comment to the various points presented (in no particular order):

Yes, I had a similar experience, will also track them down. Wuh'evuh....  Bler. People, people! Ugh.. no! Indeed. Not without asking. Bler.. Dogma... No shit!!! Why would they?  Right On, D McS!!  Yep. Yep. Hearsay... Yeah, really? What are you TRYING to say.  Really? OK.  No.Not gear, people. Not people, relationships.  etc etc etc...
