If you were not using a dual polarized rail supply, then you would
have problems because the design would force you bias the IC so that the

a decoupling cap.


No, you'd need a COUPLING capacitor.

Ignorant sap sucker.

Go back and count your marbles, I think you've
lost some.



There is nothing wrong with using a wrong term, but why show your ignorance
over it by arguing when someone corrects the term? It is, after all, a
coupling capacitor.

Yes, that is true, It's also termed Decoupling capacitor because of the interaction of what it's used in.
Coupling a circuit via a capacitor is just that, coupling. how ever,
using a CAPACITOR to isolate DC voltage (which is where the original contents of this started) is termed as Decoupling capacitor which is more to describe in what it's doing and not what it is.

Any one that has really been working in the field knows this how ever,
I find those that just sit there arm chair wise and recite text book literature and proclaim to be experts are just ignorant to say the least.

Graham, or is it Mr. HAM? the little snake in the grass.
