Smile KOEFFICIENTS ( k ) - useful for audio electronics

hi
lineup here, with some info

Useful koffecients for electronic calculations .
Besides Ohm's, Kirchoffs Law
there are some k-values that are generally often used
in electronics.
To learn these and memorize them is a good thing.

I bet there are cofficients you know of
that I even never have heard of
But I am ALWAYS willing to lear new stuffs .. if I have any use for it, that is.

Why pick up & carry around knowledge, you never will use.
It will not be optimal use of brain cells.
Better fill cells of your mind with something more positive and good.
Don't you think ?

-----------------------------------------------------------------------


I can start with give you 3 of my favourites:
Lets call this little family of three: kA, kB, kC
They are relatives, related.

Quote:
Useful k (koefficients) are:
where pi ~3.1416
==================================

1
-------- = kA
sqroot(2)

2
-------- = kB
pi

kA
-------- = kC
kB

Which gives us these values:
------------------
kA ~0.707
kB ~0.637
kC ~1.11


kC can also be described:
pi
------------
2 x [sqroot(2)]

or in real numbers:
3.14
-------
2.83

So when does The Lineup Audio Labs factory
use these above koefficients?
Answer is
- Most often when we need to
buy TRANSFORMERS for our amplifiers.



regards lineup

Default Don't forget kG!

A useful thread but sadly too late for me.

I neglected the gravitational constant (6.67300 × 10-11 m3 kg-1 s-2) when starting my latest amp. It ended up weighing 36.7kg (without tubes)...

Worse, KG turned out to be even higher than that.
I've wondered myself many a time which Ké coefficiënt K-K-K-Ken was refering to in the movie "A Fish called Wanda".

Fortunately tubes are vacuum filled so they should cancel out some of the weight. Use a lot of tubes.

Smile Archimede, Pythagoras Newton & Babylon - SQROOT of 2 ... and PI ... and ... Audio

hi

anyone wonder about me pointing out
two important values in my Intro:

SQROOT of 2 = 1.4142
and
PI = 3.1416


Has anybody else figured out
why these are so useful
when it comes to audio electronics.

As most in our
western civil-?-ization
it begins, goes back
to greek scientists


some guys of above average in wisdom & style
in this case, among others:
Archimede & Pyhtogoras
who did some work on The Circle

But no way they were the first!!!

The Babylonian tablet
Year Before Jesus Christ of Nasareth 7289
gives an approximation to \sqrt{2}
accurate to nearly six decimal places.

Pythagoras was interested in music and the Pythagoreans were musicians as well as mathematicians.
He wanted to improve the music of his day,
which he believed was not harmonious enough
and was too chaotic.
Pythagorean tuning
is based on a stack of perfect fifths,
each tuned in the ratio 3:2, the next simplest ratio after 2:1,
which is the ratio of an octave.
Regarding Gravitation & some fundamental konstants we still use:
