I invented a 2-phase DC battery pack

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

Infinity is a *really* big number and WRT time, makes for a long wait. ;-)

Hi, Are you talking to me? I worked on TTY too B4 I changed my career path. Then you counter EMF or fly wheel effect, things like that, Eh? Educated... I was in a p[osition to educate, Many times I was an instructor in many different gears and subject,

Between two test leads, and fast enough it'll sown sine wave. Sine wave is integrated kazillion sq. waves of diffferent amplitudes . Thompsons theorem, right?

Hmm, Learn what without theory. Experience alone does not cut it. You have to have both. Feels like I am back at school sitting in a class room or lab.

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

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

You *obviously* need to be back there because you never learned even the basics. ...'nother freakin' Cracker Jax engineer.

WTF???

Square waves are composed of sine waves: Fourier.

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

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.

Hi, By any chance you have any one who worked at Honeywell? Ask him about Gold tiger ring.....

Do you know by any chance wwhol worked at Honeywell? Ask him about Fred Miller award and gold tiger ring.

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..

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.

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!

You really are as stupid as you sound. Amazing.

No, not this time either, stupid.

The "other one" doesn't matter a crap. The fact is that "square waves" don't exist in reality, either, stupid.

What a dumbass!

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.

I remember the first class I had in trigonometry. Most of the time, the teacher was going around helping students find the (sin / cos / tan) keys on their calculators. There was nothing said about what trigonometry is, or why you'd want to use it (other than passing that test).

I have a great old Pickett circular slide rule that had two plastic index arms that would set to the numbers you were working with. IIRC, it was more accurate than a twelve inch slide rule but only on the outermost scales. I have a number of those - plastic, bamboo and aluminum -as well as beautifully chromed K&E drafting sets that are all pretty much obsolete. I still use vernier calipers and the B&S micrometer that I bought way back then, but all the protracters, triangles, french curves, lettering guides and Rapidographs are lying in a box somewhere, mouldering.

There's something that a slide rule teaches you about the elements of mathematical relationships that you just can't get from a computer.
