Therefore,

A balun doesn't provide the same common-mode rejection
as a high impedance differential input (because degraded by
impedance interactions). Noise immunity is conferred by
the differential input, and *not* by the "balancing" per se.

This thread is typical of Usenet discussions where terms
are assumed rather than defined. Folks could understand each
other better if "balanced", differential", "floating" and
"common-mode rejection" were included up front. But hey,
that's life in cypherspace, ain't it?

And "balanced" is far and away the worst offender. Almost
universally misused.

Now here's a related question for all the Buckeroo's:
What advantage does a balanced-in-the-sense-of-equal-
voltages-and-equal-source-impedances-to-each-polarity-output
have over a balanced-in-the-sense-of-equal-source-
impedances-to-each-polarity-output-but-only-one-polarity-driven,
and assuming a true high impedance (non-interactive)
differential receiving input?

Much thanks, as always,
