     This code shows real-time smoothing of noisy data using two algorithms. The first is a FFT (Fast Fourier Transform) method that is used in image processing. The second algorithm is the Savitzky-Golay technique, which uses a quadratic least-squares moving window. This program allows the user to create noisy data with a varying number of points and randomness, then apply different smoothing settings on the data. A graph updates the data after each smoothing event. Easy to apply to any data - Microsoft should have included this with Excel (The Excel moving average function is very weak).

Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net
