Here's what my genius mind came up with.

First I obtained a standard D-cell battery pack that holds 2 batteries in series.

Next I installed a center tap between the two batteries in the battery pack.

So now I have a series battery pack with three terminals:

L1 is the (-) negative terminal on battery A
N is the center or neutral tap between battery A and B
L2 is the (+) positive terminal on battery B

So to prove I have 2-phase DC, I connected a dual-trace oscilloscope as follows:

The reference leads from both probes were connected to the center neutral tap.
Probe A was connected to L1
Probe B was connected to L2

As I expected, the scope showed a 1.5 volt positive phase trace and a 1.5 volt negative phase trace.

Clearly I have 3 volt 2 phase DC.

The only thing left to do is submit my paper to IEEE.

Troll. Phase has no meaning on DC. 3 wire / 2 voltage DC goes back to
Edison if not farther.

It depends on what the meaning of the word 'is' is....I mean 'phase' is.

Connect a vibrator from an old tube type car radio and with the proper

Hi,
If I measure battery output with 'scope, I don't see any slightest sign
of wave form. Not even a noise. How come? We have distinctively separate
DC and AC thpory. Ever heard of impedance in DC circuit? It is
resistance only. If that is not the cae, we have to redo all the theories.

The theories are good, you just need education on them.

One simple thing is the old teletype machines. They work by turning DC and
on off in period of around 22 miliseconds to select the leters to be
printed. The coils have an inductance of around 1 henry. While they will
pull in the levers with as little as 10 volts, it will be too slow for
correct printing. It takes so long for the DC to make its way through the
coil and the maximum magnetic field to be generated. One way around it is
to use around 150 volts and a series resistance of 2500 ohms. This keeps
the overall current down but lets the levers pull in faster.

At some point, the batteries were manufactured, looking at it that
way... Someone put them into the battery pack...

Hmm,
To increase voltage but not the current and also to minimize counter
EMF. As well you know fly wheel effect..... Education is to teach the
theory by understanding the math behind it and through experiment to
confirm it in the lab. Theory without real life experience is useless.
First thing I learned after leaving school, on the first job site.

Today's young engineers hardly do manual calculations. They just tap the
keys on computer. When I showed my son old slide ruler i used to use,
the look on his face....He is a consulting engineer in civil.

No, you just have to learn something. The theories are all cool with
reality.

Hmm,
Learn what without theory.

You flunked English (basic literacy), too, didn't you?

Experience alone does not cut it.

Don't make me laugh. What a *STUPID* statement.

You have to have both. Feels like I am back at school sitting in a

What you have then is a 32 nHz (nanohertz) square wave.

WTF???

Sine wave
is integrated kazillion sq. waves of diffferent amplitudes . Thompsons
theorem, right?

Square waves are composed of sine waves: Fourier.

You spew this crap and ignore the little thing of "infinity". Do you
have a brain?

Very funny you know that and not the other one?
We are talking pretty well same thing. Integration
and differentiation. Fourier used these.

Sorry Tony, but krw is correct on this one.

Fourier postulated that every periodic wave could be represented by the sum of a series of sinusoidal waves.

So far as I know, the vice versa isn't true. You can't represent a sinusoidal wave as the sum of a series of square waves or saw tooth waves or any other kind of wave (spherical wave) for that matter..

A Pictorial Introduction to Fourier Analysis/Synthesis

If that were the case, then anyone explaining Fourier Synthesis would make the point loud and clear that you can represent any periodic wave as the sum of a series of ANY KIND of wave, square, sinusoidal, sawtooth, take your pick. But they don't say that. They say that you can represent any periodic wave as the sum of a series of sinusoidal waves, and they stop there. So, the idea that a sine wave can be represented by the sum of a series of square waves just doesn't work for me.

That's because in Fourier synthesis, there is a mathematical relationship between the waves comprising the series; you just can't hobble together various sine waves of varying amplitudes and frequencies to get something that fits. There has to be a mathematical expression by which one can determine what each wave in the series to be summed should be.

Hi.
Didn't I say the same? This is how DAC, ADC circuits work, No?

Nestork-

That is exactly what a college professor wrote a paper on, over 50 years
ago. As I recall, he used a series of step functions to synthesize
other waveforms, and suggested that the process was not restricted to
sine and step.

My memory is getting dim, but I think the paper was written by Dr. Wayne
Chen, who became chairman of the department of Electrical Engineering at
the University of Florida in the late 1960s.

I think the mathematics involved in the use of sine waves may be much
simpler!

Here's what my genius mind came up with.

First I obtained a standard D-cell battery pack that holds 2 batteries in series.

Next I installed a center tap between the two batteries in the battery pack.

So now I have a series battery pack with three terminals:

L1 is the (-) negative terminal on battery A
N is the center or neutral tap between battery A and B
L2 is the (+) positive terminal on battery B

So to prove I have 2-phase DC, I connected a dual-trace oscilloscope as follows:

The reference leads from both probes were connected to the center neutral tap.
Probe A was connected to L1
Probe B was connected to L2

As I expected, the scope showed a 1.5 volt positive phase trace and a 1.5 volt negative phase trace.

Clearly I have 3 volt 2 phase DC.

The only thing left to do is submit my paper to IEEE.

Ok, now do this. Take two 12 volt car batteries. Center tap just like
you did. Put two starters on your engine. One starter will go
clockwise. the other will go counter-clockwise. Have them both turn at
the same time, and your engine wont start! How is that for genius?

A perfect analogy. DC is simply AC with a frequency of zero!

Hi,
If I measure battery output with 'scope, I don't see any slightest sign
of wave form.

Then you have no clue what you're doing with an oscilloscope. I use
mine on "DC" signals daily.

Not even a noise. How come?

You're incompetent?

We have distinctively separate
DC and AC thpory. Ever heard of impedance in DC circuit?

Absolutely. You've never heard of a "Thevinin impedance"?

It is resistance only.

Wrong. It has an impedance. AT DC, it has only a real part but
again, DC doesn't exist in the real world.

If that is not the cae, we have to redo all the theories.

No, you just have to learn something. The theories are all cool with
reality.

Hmm,

Since you're a genius, perhaps you can do what no one else
here except myself has been able to do and that is give
a definition of the electricl engineeing term "phase".
You have 10 people pontificating on it, yet not one of them
can define it. I gave the defintion a week ago.

Is it possible for you to disagree with someone over something without insulting them?

It makes you look like a 14 year old when you do that.
