The word is xenophobic, you good for nothing eastern european trash, and
you're wrong about that- please visit the US so we can make you a
permanent part of the landscape.

Right Fred, You aren't afraid of foreigners - which is what xenophobic
means - you merely hold them in contempt, which is chauvenism, a word
invented by the French. As an attitude, it is all too popular in the
U.S., but in this particular case, the Chinese and the Japanese are
even worse.

It is - of course - a thoroughly demented attitude. Sensible people
judge other people as they find them, rather than assuming that
everybody in some racial or national grouping is identically inferior.

Just as a matter of interest, why should I be a more suitable source
of help than you for someone posting from Iran? I'm quite a bit
closer, but distance is nothing on the web .... ideologically, I can't
see much difference between the ayattolah's in Iran and the religous
right in the U.S., both of whom seem to have worrying ideas about
their fitness to control nuclear weapons.

Hmm ... I don't think I feel qualified to determine if it's out of his
reach. After all, his questions on all the other threads sound like
something I would have asked 30-35 years past, and I turned out okay
;-)

I'm not qualified to answer that! :p
It's only 2.7 GHz, IIRC. Lathargic ... close to D.C. I'm envious. Back
when I was in college, they didn't have such devices as they do today
... so easy to match and use at low GHz ranges.

Hmm... analogue is not really my thing, but to me 2.7GHz is fast enough to
steer clear of.
Having a few failures behind him will certainly improve his outlook,
not dash his dreams, IME. Trying projects beyond one's ability is the
mark of a person who will learn rapidly, IMHO.

Failing when you're being marked is not good! I kind of agree, learning by
trying it is clearly the best way.
Whatever discouraged you in the past, it sounds like you have had some
experience since.

I was involved in Formula Student (FormulaSAE over the pond) and we tried to
do a little too much and didn't quite get it finished in time to test it and
solve the little issues you get with any prototype. Needless to say we
didn't race and all of our hard work was never really brought to fruition
when it mattered. Seeing 11 of the guys you've worked with over the course
of a year that frustrated and disappointed is a shame. I was the only
person who had driven it at the end of the competition so I'd at least got
that out of it.

We have since raced it and the car performed extremely well, we beat the 4
other cars we were up against (it was a small figure of 8 track, we beat
them almost entirely on the fact that we lifted our rear inside wheel much
less than anybody else). One of the cars we raced was the best UK car in
the competition. It's the most fun thing I've ever driven.
I realize you are trying to be pragmatic, but the OP
is just looking for advice on a spectrum analyzer circuit, I presume.
It's not that complicated.

If you insist :)

I still feel that the guy has a little too far to go, will experience a few
too many problems through never having done it and learning everything the
heard way and will probably be dissapointed if/when he doesn't achieve what
he wanted. Maybe he'll prove me wrong.

It can ALSO mean hatred of people or things foreign or strange.

For some reason Fred reminds me of an American Beauty.
One of my favorites. The military guy (the father of the teen drug
smuggler) utterly hated gay people, but in the end it turns out that
he is one. He had been struggling inside and actually hating himself
for what he knew he was.

So maybe Fred is East European socialistic trash, just won't admit
to it :)

I'm out of this thread, it might get bloody long and hot and counterproductive ;)

from payam:
hi. all i am on forth year of electronics enginnering , and love my
branch and allways likes to do new project , and wanted to you to help
me buy any one says from us , the other about my scientific quastions(
modulation on x ray) souspition the other nuclear weapones other ...!
any way!
now i am working on 140MHZ spectrum analyzer , but i think the range
of frequency is low! and the other problem i should give the ramp to
oscilloscope , so oscope is essential but i want a new way to don't
use oscope and spectrum can be seen on pc , and since my frequency is
higher than paararel port so i should use doencounter similar super
hetrodine and use ADC , does typical ADC support 10MHZ as rf in?
nothis the so low amplitude)is there a point that i should notice to
it ? for higher frequencies i should use more stages for doen
coonverters ,so on the NI.COM for the PXI-5620 Digitizer Module Block
Diagram has some idea , but i have problem whit that so any help!
please note that my frequency isn't audio! so don't shoe me software
on the web as spectrum analyzer for pc !!
again any help would be most appriciated

Not according to the Complete Oxford Dictionary - they give just one
meaning, "fear of foreigners or strangers". It is taken directly from
Greek, and "phobos" is fear, not hatred.

Mifflin Company does include hatred as well as fear in their
definition, but this spinelessly enshrines sloppy use by the
illiterate.

C'mon Bill, meanings evolve.

Fear or contempt is probably appropriate. Hatred may be a little strong.

Yes, I know. And it dates back only to 1922, a very new English word
by most measures.

Indeed it does:

NOUN: A person unduly fearful or contemptuous of that which is
foreign, especially of strangers or foreign peoples.

....as does The Columbia Guide to Standard American English. 1993:

"Xenophobia is hatred or fear of strangers or of anything foreign or
strange, and a xenophobe is a person who has that hatred or fear."

I suppose we can add <spit> "prescriptivist" to your list of alleged
sins, Bill. ;-)

Dictionaries are supposed to document language usage, not dictate it.

The word has been used in this way for many years in North America.
Consider also the even newer "homophobia" (1969), where the usual
meaning is "contempt".

Hmmm- the modern meaning of "-phobe" is actually dislike or hatred,
despite the Greek root for fear. The OP is from Islam and the reality is
that Islam is united in the single-minded cause of destroying America.
The same goes for these welfare riffraff from eastern European communist
block countries.

Now that is a demented attitude. When it comes to dealing with vermin
from a deceitful race, then the *only* consideration is circumstance and
nothing else.

My word of advice to US citizens and probably some citizens of western
Europe is that it is a felony violation of export control act
provisions to give this individual any information concerning the
construction or operation of a prohibited technological item such as a
SA. Private emails will be intercepted as well.

That's poorly thought-out political brinksmanship. The
idea is to appeal to the "fear isn't manly" meme. I guess it
only works on Rednecks with an education...

The addendum to the Complete Oxford treats it as proper word, rather
than compounding of Greek roots, and their first example dates back to
1909, though there is it appears as "xenophoby"
Indeed it does:

Absolutely.

Dictionaries are supposed to document language usage, not dictate it.

Etemological dictionaries list the original, historical meanings of
words, and their modern corruptions - this documents usage in a useful
way. Non-etemological dictionaries, like the American Heritage and the
Columbia, are excessively descriptive, in that they seem to be giving
equal weight to the uninformed useage.
The word has been used in this way for many years in North America.

Too few North Americans are careful about the way they use words - few
seem even to know the difference between "anticipate" and "expect", so
it is unsurprising that many of them don't know the difference between
xenophobia and chauvenism, which are much lower-frequency words.

This sort of ignorance in readers impairs their comprehension of
English texts, and has to be seen as a defect in understanding - one
that we all suffer from at some level or other, when it comes to more
or less specialised vocabulary (do you know the difference between a
soffit and a bargeboard?) but xenophobia and chauvenism show up in
most people's passive vocabulary.
Consider also the even newer "homophobia" (1969), where the usual
meaning is "contempt".

That is a more modern coinage from ostensibly Greek roots - "homo" in
Greek just means "same", so neither root is being being used in its
original sense - if you read it with the Greek roots in mind, you'd
expect it to mean something like "non-conformist" or "easily bored",
so the Greek roots aren't really relevant to the meaning.

Xenophobia seems have been coined by Victorians who were showing off
their knowledge of Greek, and the meaning of the Greek root words is
relevant.

This may be your opinion, but if you look at clinical phobias, it is
all about fear, with a consequent aversion.

that Islam is united in the single-minded cause of destroying America.
The same goes for these welfare riffraff from eastern European communist
block countries.

One wonders about the "reality" where Islam is united or single-minded
about anything.

Generalising the opinions of Al-Qaeda to the whole of Islam is as
realistic as regarding the fundamentalist Christian right in the
U.S.A. as representative of all Christians. Lumping the "welfare
riffraff" of eastern European ex-communist block countries into the
same world view represents a comparable level of irrationality.
Now that is a demented attitude. When it comes to dealing with vermin
from a deceitful race, then the *only* consideration is circumstance and
nothing else.

Assuming that you can identify a national or religious group as a
"race" rather begs the question. Once you have identified them as a
"race" - and in recent years only the Nazi movement have had their
heads far enough up their ideological arses to espouse this particular
bit of pseudo-science - you then have to demonstrate that the whole
"race" is deceitful, which you might find difficult.

You definitely do seem to be exhibiting an irrational world view -
granting that you don't show any other signs of dementia, one can only
conclude that you are suffering from some kind of post-traumatic
stress disorder, possibly associated with your military service. The
experiences which you have posted here about that period were horrific
enough to justify an irrational reaction or two, and you wouldn't be
able to post about something that really shook you up.
My word of advice to US citizens and probably some citizens of western
Europe is that it is a felony violation of export control act
provisions to give this individual any information concerning the
construction or operation of a prohibited technological item such as a
SA. Private emails will be intercepted as well.

Bah. The Export Control Act was one more non-tariff barrier to trade -
Cambridge Instruments couldn't sell S.200 electron microscopes to
Russia because there was a 6502 processor in the keyboard, while
American firms always seemed to be able to get exemptions allowing
them to sell serious technology.

Try to prosecute somebody under that act, and the defence lawyers
would use ridicule to make mince-meat of any prosecution. The U.S.
enthusiasm for one-sided "free trade" is already widely seen as poorly
disguised colonialist exploitation, and a high profile trial that gave
the defence a chance to high-light yet another U.S. trade scam is the
last thing you can afford at the moment, now that Enron and similar
book-keeping frauds have scuppered the capital inflow that used to pay
for your enormous trade deficit.

Your "advice" is empty bluster, no whit more realistic than your ideas
about a single-minded and united Islam.
