Oh so true. At least half the equipment I see doesn't even have the Logo
proportioned correctly despite the design being readily available online and
easy to understand. Typically the C and E are too close together.

Philips / Ferroxcube ? I used one of those plus some Y caps to get a piece

Those dual hole ferrites are a real boon.

Good for making balun.

You obviously know nothing about shielding or emission standards.

You obviously replied to a troll. You lose.



Your capacity to make a valid assessment rests at nil. You're a

At home, I often use some screened audio leads which carry speech
signals at about 100 to 200 mV. The leads may carry one or two
signals (mono or stereo) and may be about 1m or 2m long. They are
not balanced.

Sometimes it's unavoidable but my audio lead has to pass near a PC
and also about 6 inches below and in front of a CRT display. I
want to avoid electrical noise interfering with the audio signal.

(1) Would it help to clip some ferrite on the audio lead?

If the interference is magnetic radiation from the CRT deflection and
(at startup) the automatic degaussing coil, ferrite will not help at
all. Wires in the presence of an AC magnetic field will pick up a
voltage. The only hope is to lay the wires parallel to the magnetic
flux lines, or get them out of the area. Only MASSIVE shielding with
Mu-Metal shields will help, by conducting the flux lines in the shield.
I suppose in theory totally enclosing the wires in a string of ferrite
rings would be going in this direction, but separate ferrite rings are
no comparison to a solid Mu-metal shield. Usually these are used to
protect CRTs, photomultipliers and vidicons from stray magnetic fields,
and they certainly do work. I've never seen it used to protect a cable.

Putting a balanced-unbalanced transformer at each end of the cable would
be another time-honored fix. Then you can have a truly balanced signal
even with equipment that is unbalanced.

HOWEVER, if they are in a twisted pair configuration, any EMF produced
ALSO gets cancelled immediately and on any and every pulse. That is the
whole idea behind twisted pair. It isn't just for grouping.

As I mentioned before, there are times when the cable can't
easily take another route so I am interested in the better
shielding appraoch which you mention.

That's the problem! Shielded audio cable is good for eliminating
electrostatic interference, which is a common cause of audio noise.
But, it does practically NOTHING to eliminate low-frequency magnetic
(inductive) interference. And, a computer monitor is exactly a source
of magnetic radiation at several frequencies. The horizontal sweep and
the switching power supply frequencies can be shielded to some extent,
but it is not really practical. The vertical sweep (50 - 100 Hz) can't
be shielded without insane effort, so the only real way out is to
eliminate its influence on the circuit. That's why professional audio
types use balanced circuits for mikes and all sorts of other low-level
signals.
Unfortunately, many web sites merrily say that almost any wire
will do for a short run of audio cable. I am not so sure!

in the presence of interference sources, clearly NOT true!
(2) For a given max outer lead diameter of about 3mm (maybe
4mm), I guess some audio leads are better at intereference
shielding than others. I'm in the UK; is there a type of
decently shielded audio leads you might recommend without
getting into really expensive stuff. (I can add the
connectors.)

Forget this diameter stuff. Unless the cables were FEET in diameter,
and almost all solid copper, they'd have NO effect on 60 Hz magnetic
fields. These fields penetrate conductors.
It would be easier to try simply using longer cable(s) to
avoid the problem spot(s).


If you can route long cables away from the source (the CRT is by FAR the
worst offender) that is the simplest approach. If not, a pair of
transformers and a balanced, shielded cable should also work. But, the
TRANSFORMERS need to be shielded! Many cheap audio transformers are NOT
magnetically shielded, just put in a pot-metal box. if they are near
any power transformers or CRTs, they can make the problem WORSE!
If you think a single wire stretched in space can pick up a signal, how
bad would 10,000 turns of wire be?

Silly. Flux lines are not *ever* straight lines, and in reality, they
are ever expanding "shells" that emanate outward from the source, so even
"parallel" wires would likely garner EMF. Though they can and are of
course oriented so that they are mostly aligned along a single axis, it
is not a good practice to think that noise abatement can be achieved by
simply aligning the conductor with the flux.

May circuit card utilize shielded channels that are merely a PCB
conductor trace over a ground plane layer with a low, narrow "can" placed
along its length.

Since "cables" are typically meant for connection between larger
hardware elements, they are also typically flexible, not rigid.

A rigid interconnection is usually not referred to as a cable, but it is
not much more than a hard encapsulation of a cable.

So they are out there, they just are not called "cables" at that point.

LCD backlight supplies can radiate a lot of junk. This is especially
interesting in things like digital scopes and spectrum analyzers.

A scope probe held near the screen of my Tek TPS2024 shows 600 mV p-p
spikes at 664 KHz. Other scopes drool lots of EMI from around the
edges of the plastic box near the LCD.

The PS in a modern, large form factor LCD display (not a PC display) is
a one piece item integrating the rail for the backlight and the rails for
the LCD and video works all together in a single SMPS. Your PC LCD
display, with its remotely mounted supply is a different story. There,
the backlight power conversion is local to the backlight curtain. Any
design with local power conversion for that will be noisy as the space
budgeted for it usually will always mean a poor design and a lot of
noise. A well made HV supply can pipe the voltage there with far less
noise. With more space for the design, it ca be made very quiet. Space
constraints cause engineer to cut corners in design.


That happens in a lot of industries. That is why some Americans stopped
buying American cars. US car makers went to cutting cost of manufacture
to boost profits and that cut in quality cost them. Less screws in the
door panel and plastic in the wrong places, and poor plastic type
choices, etc. Now, even though they are far better quality cars, those
folks have not returned as customers, and still have misconceptions about
what is in the market.

Sorry, I should have used the 2nd person plural, "y'all."

Proving that it is really you that is semi-literate.


The English didn't provide us with a second person plural, like
sensible languages have, so we had to invent our own. In the South,
it's "y'all." In the Northwest, it's "you guys."


In upstate New Yawk, it's "yous" or "youz guyz".

Sure we did - "you". Second person singular is "thou".

Only kidding. In Middle English we had a special letter, which looked
like a "y" but with a dot above it. It was pronounced "th" and that is
where the confusion started.

In modern Icelandic they still have two versions of "th" - one voiced
as in "this", and one unvoiced as in "thin". The voiced one is written
"th", but the unvoiced one uses a letter called thorn, which looks
like a lower case p, but with the vertical stroke extended upwards.

So now you know....!

Do you know anything about electronics?

Unlikely, I guess.

Standard English USED to have a second person SINGULAR, which was "thou."
You was the the second person PLURAL but became used as singular due to
either excessive politeness or widespread ignorance or something of that
sort. Eventually, people couldn't stand the ambiguity, but instead of
resurrecting the old thou, which everybody except readers of Shakespeare
had forgotten how to use, they came up with new plural forms.

Where I used to live in Texas, y'all was nominal second person plural,
inclusive and polite, very much like 2nd person plural in many other
languages. It is often used to address single persons when one intends
to convey friendliness or politeness or inclusion in a group. One uses
the singular and definite you when you intend something very definite as
to person, like: "Billy, you get in here right now and clean up your
mess." or "I love you."

Kentucky is in the Northwest? You mean the Kentucky that's just next
to Oregon?

Doesn't matter where he lives, he's AlwaysWrong. Kentucky isn't even
in the Mid West.
