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.


It's not called anything of the sort. You're just making stuff up as you always
do when (as usual) your mistakes are found out.



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.


Utterly WRONG.

You can call it a DC blocking cap OR a coupling cap. But it is NOT a *decoupling*
cap !



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.


You are the most monumental moronic fuckwit.

" In electronics, decoupling refers to the preventing of undesired coupling
between subsystems via the power supply connections. Nowadays, this is commonly
accomplished by connecting localized capacitors close to the power leads of
integrated circuits to act as a small localized energy reservoir; these supply
the circuit with current during transient, high current demand periods,
preventing the voltage on the power supply rail from being pulled down by the
momentary current load. See decoupling capacitor. "

Arm chair text book rookie!.

All show and no go!.

Don't feel alone, I work with them
quite often. All living in their ideal
world!
There are many very smart and talented
people in this group that I say deserves a lot
more gratitude than what they get. You how ever, aren't
one of them.

Now go count your marbles and go to bed. Let some one
else use the community computer.
