So you are saying any two hex numbers that fit the sequence will do- it
does not matter that it's a "match processor"?

BTW- what is modern social "lingustic" terminology? Did you graduate

That's not base 4- you mean base 60.

Math Processor is simply a support for the understanding of the sequence,
but not required to solve the problem. Look at the hex sequence, your
ability to think in and out
of the box is required. This test is used by Microsoft and others to see if
you are able to think beyond what you
think is the direction to solve a problem. It took me about 8 minutes to
solve it. I'll give you a hint,
your hex calc won't help you solve this one.

It's a post-idiom term from the old "say it, but don't spray it", realizing
people spit when they talk,
youth has termed the Spit as "output" from the source. Spit means to output,
to say, used in modern
social situation by younger generations.

That's a defamation and it means you are still reeling from getting your
ass handed to you for your worthless erroneous statements about the
OP292 single supply dual amp rectifier circuit. This made your queen ego
mad as hell so you turn into a bitchy little slanderer- isn't that typical.

His posts are generally delayed, which means
he went to the trouble to do research before responding, which would
be admirable except for the motivation.

In the case of the OP292 thread, the motivation was to make a dead
certain diagnosis of the Nazi Clarence and his problem- and that is what
I did- also ordered some OP292's and played around with it some more.
But you go ahead with your trumped up bullshit claiming to understand
someone's motivation- and your PhD in Psychoanalysis is from where?
There is a name for your kind of sickness where you *know* what people
are thinking-pathetic.

What Fred et al never do is try to be genuinely helpful, social,
whimsical, truly interested, creative, or fun.

You are such a boring p.o.s. the last words to describe you would be
creative and fun- you are a damned boring hack, nerd, fr[w]eak, and
possibly a queen.

So don't pay him undue attention: he's not nice and he's not
important.

Yeah? And just exactly who the hell are you to set yourself up as the
"importance rating" authority on SED? Your problem is you just hate
anyone who is not impressed with your trash- you have to be surrounded
by morons- and I'm not interested in what you call them- anyone who
could put up with your laughable pretense of a life is a moron.

Hi,

Does anyone have a 9V 1A transformer schematic? I want to
integrate it into a project to run a disk drive. The smaller the better.

If you don't need a very accurate or stable 9V, note that 6.3V * sqrt(2)
is fairly close to 9V. 12.6V transformers with a center tap are quite
common. One of them, a dual Schottky diode, a large capacitor and
something to limit the inrush current will give you about 8.5V on the
average day.

If you need a more accurate voltage, I suggest you make an
unregulated supply that is more than (9V + 2V) * 120% = 13.2V and follow
it with an LM317 type regulator on a good heat sink.

No- I liked the OP292 and want to experiment with more applications- the
newsgroup thread was lost in the noise floor of my interest.

Correct! You are the man!
Fred could not even understand where to begin. He was busy counting his
toes.

Do I win anything?

A congrats will have to do or I could get you tickets to amateur comedy
night show starring Fred Blogger?
Ignore Fred, he's mad at me because I outwit him everytime and he can't get
under my skin.
I'm actually starting to like that old misfit..... Share some of your love
Freddy! Give Ken a taste of
your comdey show routine. Go for it, the stage is yours:

LADIES AND GENTLEMEN, WELCOME TO AMATUER COMEDY NIGHT. TONIGHT WE

Freddy,

Don't get upset, you know haow bad it affects you ulcers and vericose viens.
Let me explain the sequence:

1FAA 0010 , 11F1A2 021101, 12F111A122 0121120111, What the next sequence?

The first set is the source:
1FAA 0010

The second set is thinking out of the box, so it's literally telling you
what the source has
1 for 1, F for 1, A for 2, 0 for 2, 1 for 1, 0 for 1

The third set does the same, now based on the second set:
1 for 2, F for 1, 1 for 1, etc....

Ken was right:

Yes that is pretty strange for even Fred and he is as strange as
they come.

The problem has been verified by Analog devices and the alternate
circuit with the diodes to assure equal amplitude are in place.
The Brass board is in the hands of the customer and the final PCB
layout is complete for the first build. The unit now works as
intended.

BTW, I killfiled FRED ages ago, so I never see him unless someone
replies to his inane rambling.

Anyway, unless I made some kind of mistake, the result of my
"simulation" is that Irms goes up significantly with capacitor
value. In my simulation I hold Idc constant, since the intent was
to design a regulated power supply. So the efficiency goes down
with increasing capacitor value.

Since Vdc increases with capacitance the output
power goes up, so the input current (at constant
Vac) will increase anyway.

Refine the experiment maybe. Do a Pout/Pin plot,
or, for all values of C, adjust Vac so that Vdc
is held constant.

LTSpice is handy for this sort of thing because
the instantaneous expression Vac*Iac can be plotted
and then averaged over a number of cycles. I found
that facility invaluable for predicting power loss
in individual components in a power switching cct.

That statement really makes no sense to me. How can you crowd the same
charge transfer into less time and get its RMS value to decrease? (For
conceptual simplification, assume the DC current taken from the bridge
is constant, so that the charge, (Idc * (2 f)), is held constant.

I re-examined my models. With a refinement of one, I can predict the
*small* increase reported by someone else. The original model assumed
that the output ripple was negligible, thus restricting the range of
filter capacitor values. If you include in the range of capacitor
values, those so small that very large amounts of ripple occur, and the
conduction angle approaches 180 degrees, you get much more change of
r.m.s current, but so much ripple is not normally realistic.

The point is that transformer winding resistance and leakage inductance
are
quite dominant in determining RMS current. Because these factors are
invisible on the schematic, I think people start to think of peak
currents
climbing ever upwards.

Agreed. Do you find that leakage inductance has a significant effect?

John, leakage inductance in rectifier transformers is a subject of interest
to me. I am moving house right now and I need time to collect my thoughts
anyway, so I would like to post or email you in a week or two when I can
