Don't be too sure about that. Everything is an allegation so far derived

the bottom of it. And the American companies, of which there were

Hey, you are ready to convict based on a grand jury subpoena.

A grand jury is an entirely different entity from the CIA Iraq Survey
Group. The so-called bribes all appear to be in the form of oil vouchers
and it has to be investigated to its conclusion. Many US companies were
involved too- why do you ignore that fact?


I haven't ignored any facts; just haven't seen any. Doubt that you
have any REAL facts, ...
That's the point- you have no idea of American corporate involvement
yet- but you have been told it is there.

When the Dems have nothing else they resort to innuendo and
outright slander. Just like you, fredrook.

Nope- that is the character of Republicans these days- and the small
bits of offal such as yourself.


Right, Dan Rather told you that.

Nope- that is more than obvious from numerous scandals that have arisen.
Take a look at that sorry-assed loser Karl Rove- clearly some kind of

I keep telling you , there is no such thing as "the" plane.



Excellent point. They will be 90 years old in 2044, because they flew
as virtual planes for eight years before they were built.

I guess I was wrong again.

The airframe is an inanimate object, its lifetime is rated in hours of

So how many hours have you been operative?

Given recent history, what 'people' are subsuming to need not be a good

Consider going into the hospital for surgery and getting an

It could also be prevented by the hospital bothering about their work - i.e.
If they are sloppy about id and medical records *now* they will *still* get
it wrong when a bored medical technician uses a machine to match the
poorly-updated medical record and the anaestesesist(sp?) don't care to watch
for life signs either, cause the system Ok'ed the anesthetic.

Hi all,

I am developing an stepper motor position control board in the

1/64) mode to an target speed of 2500RPM for an stepper motor with 200
step resolution.

Big problem here. 2500 RPM = 41.66666 revs/second

41.666 revs/second x 200 pulses/rev = 8.333 kHz, NOT 3 MHz.

Re-work your calculations using the correct speed formula and the answers
will be much more manageable.


my
timer freq which is 40Mhz is greater than the 3MHZ.Whereas in the case
of microstepping(1/64) the stepper motor can rotate 12,800 steps
/rev.now if want to reach an target speed of 2500RPM by using
microstepping(1/64) the target velocity will be (2500*12800*60)1280Mhz
which is less than my timer freq 40Mhz.Is this the problem for my
speed,or else my interpretation is wrong.Please clear me regarding
this speed of an stepper motor in the microstepping mode.

Sudheervemana.

Yeah, sure. It sounds like more of a plausible excuse to install RFID
chips in the gullible masses and it still won't stop mistakes being
made.
I know of a case in the UK where a guy went into hospital to have his
leg removed. Fearing some mix up, he wrote "This one" on the leg that
was to be amputated and "NOT this one!" on the other leg.
Unbelievably, the surgeon still managed to remove the wrong leg! :-(

That gives you a physical model, but how do you connect the darn thing
to a SPICE simulation?


Easy. Spice has direct support for transmission lines.


I do not think a real telephone line is going to be amenable to
simulation with a simple RLC. It's going to act like a transmission
line, with a characteristic impedance somewhere centered around 100
ohms but varying widely from one to the next, a widely varying
reflection coefficient, a great deal of loss, also varying, and with
a length that can be anywhere from a few feet to a few miles.


Spice has a real T line that has RLC parameters.
But alas, we also need G and all four are functions of
frequency though C and L are not greatly varying.

Hey there,

I'm thinking of making a DDS function generator using one of the AD9x
chips. All of Analog's DDS chips are in SMD packages. I've emailed
others who have made these in the past based on the 50 and 125MHz
10bit chips and they recommend going with one of the better chips for
a cleaner output. So I'm possibly leaning towards the 400MHz 14bit
chips.

I wanted opinions on mounting one of these on a homemade pcb ( similar
to this: http://protoboards.theshoppe.com/qfp_0_8_mm.html ) then using
short jumper wires to connect it to the rest of the circuit. This way
I would only have to solder the chip once (by hand). The board and
chip could easily be removed for use in other circuits or revisions.

My worries are it may cause too much noise or interference in the
output. I don't have much experience in these frequencies so I wanted
to ask what others thought.

Thanks,
Burnboy
I wouldn't do it.

But if you DO do it, make sure you get bypass caps and analog power supply
filtering on the same PCB as the DDS.

Also, those DDS's run pretty hot, and have thermal pads on their
underside, I believe. You may have problems with overheating if you hand
solder and don't connect the thermal lug.

Have you thought about building your prototypes in a toaster oven? I
haven't tried this yet, but I would like to try it soon. This would save
you from hand-soldering.

Hi Ian,

Thanks for your suggestion. TBH we've dismissed that approach in the past
since a decreased slew rate could increase jitter on the signal. Jitter is a
problem to audiophiles (real or perceived), so limiting the slew-rate is not
something we want to do if we can at all help it.

That's a non-news story because the whole purpose of the snow bird
program was to get the support in Florida from areas where it was strong
enough to not need it. This fits New York and California well- those
states are strong for Kerry with +20 leads. So unless you have hard
numbers and facts, the Post story is just moronic speculation- which
fits well with your mentality.

Some 46,000 New Yorkers are registered to vote in both the city and
Florida, a shocking finding that exposes both states to potential
abuses that could alter the outcome of elections, a Daily News
investigation shows.
Registering in two places is illegal in both states, but the massive
snowbird scandal goes undetected because election officials don't
check rolls across state lines.

The finding is even more stunning given the pivotal role Florida
played in the 2000 presidential election, when a margin there of 537
votes tipped a victory to George W. Bush.

Computer records analyzed by The News don't allow for an exact count
of how many people vote in both places, because millions of names are
regularly purged between elections.

But The News found that between 400 and 1,000 registered voters have
voted twice in at least one election, a federal offense punishable by
up to five years in prison and a $10,000 fine.

Of the 46,000 registered in both states, 68% are Democrats, 12% are
Republicans and 16% didn't claim a party.
