You can learn all you need to write your own FFT routines in any
number of languages for free from the Internet (not as good as a book
or a course, but good enough). You unwillingness to learn the
language of mathematics on which fourier analysis is based or the
programming languages freely available code you have been directed to
does *not* make it a secret. It's just hard.

Either someone is serious about helping me here
or please do not post to this thread.

I am seriously trying to help you, as are others. It's highly
unlikely anybody is going to write a lengthy tutorial just for you.
People are generous, but not that generous.

You say you have Fortran and BASIC available to you.

Here is a library which can be used in Fortran. It is written in C,
but as it is a library you don't even need to look at the source code
(but you can if you like). It has good documentation and links to
explanatory material on FFTs.

http://www.fftw.org/

Here is some code apparently in BASIC that performs DFTs (not quite
FFTs, but you get the same result). I've not tried it myself, but it
appears to be close to what you want.

You are not telling me what I need to know here
What I need is 500 discreet spectrum points
on 1024 samples of data showing energy
vs frequency and nothing more but I need to look
at a frequency between 100 seconds in period and
maybe one or ten hertz.
If you have the executable code and know how to use it
why can't you take my raw data and analyze it for me.
It would be much safer a thing then me trying to run
a exe file on my machine from outside sources.
I do not know what you mean by top posting.
If you are forcing me to some kind of convention
you need to take a hike because I am through
with following orders here gestapo tactics can
take a hike.
Your offer just exacerbates a preexisting condition
if it does not solve my problem here without any
fancy conversions. I have no "C" capabilities
and have no intention of learning it when
there are much nicer things like Basic and FORTRAN.

The FFT was never a military secret. The two guys who discovered it,
Cooley and Tukey, published it all over the place. It was very exciting
(you can tell from the textbooks written at around that time) and made a
huge impact in the Electrical Engineering world, because a large number of
things which had previously been impractical were suddenly practical.
Obviously it has loads of military applications, but it was never secret.
(Unless you are alleging that the military secretly knew of the
Cooley-Tukey algorithm prior to those two disclosing it. Not impossible,
but not likely, either.)

I have a simple FFT routine written in C. If you want me to post it, I
will (if you can think of somewhere topical). But I will tell you right
now, I have spent many, many hours trying to get a real deep intuitive
understanding of the FFT, and I have never succeeded. I know what it does,
but I don't feel totally comfortable with it anyway. And to tell the
truth, I think most people who use it regularly have never implemented it
and don't necessarily have any better understanding of it than I do.

The FFT function itself is only 30 lines, but there are a number of
supporting functions and structures.

Good Grief, an FFT *is* math. You seem to want some sort of Zen math
that's not math. You may as well ask for somebody to write down all

An FFT is a mathematical transformation from the time domain to the
frequency domain.

That's it.

This totally trivializes the FFT. It might be a good description of a
discrete Fourier transform, but it says nothing about the insight of
Cooley and Tukey which allows people to calculate discrete Fourier
transforms much faster than they ever had before. In other words, the FFT
is a miraculously fast way of calculating discrete Fourier transforms of
data series. The original Cooley-Tukey algorithm only works when the
number of elements in the data series is a power of two (2^n, where n is
an integer), but there are ways around this limitation and variant
algorithms inspired by Cooley's and Tukey's insight.


If you don't have the maths to understand it, well, there's not much
anyone other than you can do about it.

As the expression goes, if you have something to say, write an equation.
If you have nothing to say, write an essay.

There is what looks like quite a good and lucid description of the
derivation of the FFT in "Numerical Recipes in C", pages 504-508. This
book, which I paid something like $70 for, has been made available
online for free thanks to the publisher, Cambridge University Press
(link below). They also describe the DFT in that book. I have not
dabbled in the inner workings of the FFT since a friend in grad school
showed me a variation he'd come up with.. many years ago.

Keep in mind that a certain level of math (equivalent to first or
second year university) is *required* to understand the terminology
and the operations.

Yes, and they've asked me nicely not to talk about that stuff so I won't.

This is not true. You are looking at what some special effects guy wipped
together to look mysterious. Even in real life (non-movies) not all water
fall displays are the outputs of real time FFTs. In some cases, the
display is showing the outputs of many sensors side by side.

It will compute in real time many discrete
spectrum points on the very same data stream as it comes in
in real time.

I imagine quite a few people reading this could build one of those. These
days it isn't that hard. Anyone who understands the FFT could come up
with the version that can be stepped in time.


[....]

The industry is guarding how it uses this knowledge so

This is true, but it isn't something to worry about. The makers of snack
foods used the FFT in secret ways. You still have the option of eating
carrot sticks instead.

I do not want to make money from this FFT thing

Since the number of points you want is low, you could use the slow FT
method. It is very easy to understand. You may need to only imagine
doing the following. Some people understand things better if they do them
so you may want to actually spend the time.


Assume a list of 8 points represent a sine wave at some frequency you want
to determine. For easier thinking, make this list represent exactly
one full cycle. Call this list A.

Do this:

Note: Chances are you can use a spread sheet for this.

Make another list of values that are a sinewave at the same frequency.
Call this B

Multiply each value in B by the value for the same element of A.

ie: B[N] = B[N] * A[N]

Notice how the positive values in A get multiplied by positive values and
negitive values get multiplied by negitive value. Now total up all of the
new values in B. You get a positive answer. Write down this answer.

Try this same with sine waves at different frequencies so that you get 2
cycles or 3 cycles and try mixing in Cosines. You can make a list of
values for the results fron sines and cosines at each frequency.

Once you understand this, you can then start working towards understanding
the FFT.

Think of a list that is 16 points long instead of 8 points long. Imagine
that this list contains data the represents two cycles of a sine function.
You can do the 8 point FT on the first 8 points just like you did above.
You can also do a 8 point FT on the last 8 points.

Now, think about how the phase of the sinewave could be different if you
only last 8 points, than the phase in the first 8 points.

To combine the FT of the first 8 points with the FT of the last 8 points,
you need to match up the phases. To do this:

Imagine we have a Cosine value of 1 and a Sine value of 0.5. Get a chunk
of graph paper and a sheet of clear plastic or thin paper. Also get a pin
or thumb tack. Place the plastic over the graph paper an stick a pin
through at the (0,0) point. Plot a point for the values on a plastic
over the graph paper like this:

Now rotate the plastic sheet around the pin at (0,0) by lets say 45
degrees CCW. Notice what happens to the Sin anc Cosine values when you do
this.

Now I think you can see how to combine two 8 point FTs to make 8
points of a 16 point FT. You have to adjust each value from the second 8
points and add them to the values in the first 8. These 8 points show how
the sine wave continues from the first 8 points into the second 8 with
a period the fits neatly into 8 sample.

The other 8 values in the FT are made in much the same way but you
subtract instead of adding. These numbers show how the sinewave didn't
come out even in 8 samples.

This is the basic step done several times in the FFT. You start off with
a bunh of 2 sample FTs then combine them into a bunch of 8 sample ones,
then into 16 and so on.

There is a government conspiracy and it has to do with money.
The industry is guarding how it uses this knowledge so
it can make money from it.
I do not want to make money from this FFT thing
I just want to analyze some data packets I have
in the cheapest possible manner.
I can not work in the high tech world because I can not get
the security clearances to do so. This country has black listed
me from such work. This freedom loving country called
the United States of America.

I suspect that there's a more prosaic reason why you
can't work in the high tech world: You've a low
tech education.

But do not despair, ignorance is a curable situation.
Stupidity, on the other hand, is forever.

Like I said before their drugs have damaged my brain and my body.
I am hooked on them and can not simply stop.
The secret Service had me incarcerated for making veiled threats
against the President and the mental health people
were ordered by a judge to force these drugs on me for a whole year.
I am now hooked on them and can not stop.
Without them I can not sleep. Sleep deprivation
is a form of torture and is used for brainwashing.
You guys really need to learn what your nice
country is capable of doing to you.

We demand that you provide a block diagram showing
how these drugs work. While you're at it, please
diagram the legal system, the secret service, and the
whole mental health system. We demand that you
do this for free, on your own time.
