Will you use two resistor for your input common mode voltage

[Boki]

I saw a design for audio circiut, I am amazing why design it so simple.

Too much difference from school...

Boki, you really should work on your English writing skills. While
just a little bit charming, your English is so fractured sometimes we
can't tell exactly what you meant to say. For example, did you mean,

"I saw an audio circuit schematic, and was amazed at how simple it
looked." Or did you mean, "... was amazed at how simple it was to
design," but then we'd wonder how you determined that.

Or perhaps you meant, "I was amazed at the simple solution to what I
had learned was complicated to design," although then we'd wonder what
you had in mind.

Too much difference from school...

Did you mean, "It looked different from anything I was taught."? But
why would that be amazing? Most industrially-produced designs look
quite different from what you find in a textbook or on a blackboard.
Your next stage of learning can be to study the production designs of
hundreds of skilled engineers, to see their approaches and to learn
new tricks. I have done that by analyzing instrument service-manual
schematics since I was a teenager. And when my oceanographic company
shipped its instruments, we always included full schematics. Sadly,
these days the manuals of new instruments routinely omit or hide the
schematics, but old manuals can be purchased on eBay, or are available
on the web in some cases.

Dear Winfield,

1. Yes, this one, "I was amazed at the simple solution to what I had learned
was complicated to design,"
2. I want to express "It looked different from anything I was learnt."

Wow, you do help me a lot, thank you very much for your advice, I really
need these advices, and I will run to catch what I insufficient.

Best regards,
Boki.

Dear Winfield,

1. Yes, this one, "I was amazed at the simple solution to what I had
learned was complicated to design,"

Yes, that's a good sentence.

2. I want to express "It looked different from anything I was learnt."

You mean, "from anything I was taught." Or, "from anything I learned."
(The latter is short for "anything I had learned," but you can leave
out the "had," which is silently understood.)

Why don't you try some more good English, and tell us what you had
learned in school, and what you just saw as a more simple alternate.

1. Ya, I knew that is a good sentence, I just copy from a good man.
2. Just now, I am studying for a good English, it needs time.

I just think it was not a very special problem to avoid
temperature/process/... variation at imporatant node, for example, input
common mode voltage of OP
When I saw the schematic on a worldwide chip provider <--- only two
resistors, so, I was amazing,
I feel what I had be challenge in school is no sense...

That's it. : )

Best regards,
Boki.

You mean, "I was amazed." What chip provider, and what was
attached to the resistors? What kind of input are you talking
about, a low-Z balanced microphone input? Details, please.

I feel what I had be challenge in school is no sense...

Oops, that sentence doesn't make sense. Try again.

If I want to express "I was amazing at that time", doesn't it ?

You mean, "I was amazed." What chip provider,

: ) Sorry.

and what was attached to the resistors?

Vdd

R
|------------> input voltage
R
|
GND

Nothing attached...

What kind of input are you talking about, a low-Z balanced microphone
input? Details, please.

Um... the part of schematic perform a high resolution signal amplifier.
I don't not like to lose any signal at this part, but there are only two
resistor to perform voltage divider for input common mode votlage of opamp.

I feel what I had be challenge in school is no sense...

Oops, that sentence doesn't make sense. Try again.

==> I feel that I be challenged from people before doesn't make sense.

Well, if you were amazed at what you saw, you need the right
English tense to say that. But if you insist that you were
amazing at the time, that means others found you to be amazing
-- they were amazed by you, not by what you saw. Is that what
you meant to say to us?

Yes, boki, sometimes we're truly "amazed" by what you write
here. :&gt

No, I was amazed that time.

You might want to say that you need to study the grammar lesson
diligently, since "study hard on"... has a completely different
meaning !^)

Those two words must be hyphenated to make it blue (but phonetically, it's
OK).

I am enjoying this lesson...

"Jim Gregory" <jim.greg@ntlworld.com> źśźgŠóślĽóˇsťDTU1e.1997$Uj4.728@newsfe1-win.ntli.net...

derived = foremost, accepted format obtained from omitting unnecessary
preposition and juggling the words
Do not add "to". If you have to, it must be "to derive"....

Now, will you get back to your (poorly-written) question in the header?

Got it.

how about:
=> is the best syntax "to" derived from these words
I alwyas write down in this form, correct?

Thank you.

[Boki]

Thank you.

but why not add "to' ==> is the best syntax "to" derived from these words.

Are they different?

Be considerate. Leaving just a little of the post you're replying to
in your reply will make it easier for us to know what you're talking
about.
