- We can try..
- 1) Here's an FFT for Excel

-
- FFT is a Fast Fourier Transform for Excel.
-
- A Fourier transform gives the frequency components of a series of data,
- or vice-versa.
-
- This function is Freeware. If you use it, strike a blow against tyranny.

- 2) But what you REALLY might be interested in is:
-
- Subject: [*] MacPhase Version 1.0.0
-
- MacPhase Update!!! ( place in app directory )
- MacPhase Update!!!
- MacPhase Update!!!
- Version 1.00t
-
- The newest version of MacPhase (Version 1.00t) is here. There
- are many new features and improvements to old ones.
-
- MacPhase is a data analysis and visualization application.
- MacPhase will allow you to import and export many different
- data file formats, manipulate that data with graphical tools, analyze
- that data with many different math operations, and graph the data
- in several different formats.
-
- Some new features over the first version released (Beta
- Version 0.9.9):
-
- -Improved plotting of line, contour, and 3D plots
- -Configurable graphics styles
- -PICT overlays to data
- -More control over plotting formats
- -Additional PostScript support
- -More flexible FFT allowing 1D, 2D, and "sonagram"
- transforms
- -Much better tool support
- -System 7.0 compatibility 24 and 32 bit modes (sorry no
- Publish and Subscribe yet...)
- -Background processing
- -More math operations
- -Copy and Paste text
- -Data Translation frame grabber support
- -Brightness/Contrast Control
- -Better importing of color look ups
- -Color look up scrolling
- -Much better "Data Movie" facility
- -Play data as a sound
- -And much more...
-
- Hardware requirements
- -256 colors
- -math coprocessor or PseduFPU
- -2 meg memory
-
- Give MacPhase a test drive and let me know what you think. I am
- working very hard to make a data analysis and visualization package
- that is useful and one we all can afford.

- 3) Mathematica (costly but does everything) - sorry son't have the number
- offhand but look in any computech rag.
-
- 4) And as well, MathCAD (1-800-695-5075 (in the States; I'm not sure what
- it would be from France, but they also have a FAX # of 1 716 873 0906 that
- should work from anywhere) makes a Mac Version, as well as Win/DOS/Unix -
- not as full featured as Mathematica, but much cheaper... They've been
- sending me a stream of "Special Offers" that started out at $139, then
- dropped to $79 and I've seen in Consumer Reports that I can expect the next
- one to be $49 or so (they got a letter from a guy whose department
- mistakenly got sent all 3 at once).
