Introduction

The Fourier Data Smoothing program produces a curve of "smoothed"

values from an original list of data. An example of this is included with

the program. This program smooths data by using the fourier transform to

filter out noise (random irregularities) in the data. The fourier transform

translates the data into a frequency spectrum where noise appears at higher

frequencies. The data is filtered to remove the higher frequencies and then

transformed back into its original form. The resulting smoothed curve can be

superimposed on the original values and viewed directly or can be graphed on

any graphing program. The main function of this program is to determine an

optimal curve for a given data set and to produce a file of the resulting

values.

The filter value must be an integer greater than one and less than half the

number of data points. Recommended values typically lie between three and

nine. The lower the filter value, the smoother the resulting curve.

The data file must be an ASCII text file containing a single column of data

points ("Y" axis values). The "X" axis is represented by the count of

individual data points. A maximum of 999 data points are allowed.

The results file will be an ASCII text file containing an equal number of

data points, each point being a smoothed value corresponding to the point in

the original data file.

Command Line Arguments

The Fourier Data Smoothing program may be started with these arguments.

FDS

Configuration

The "config.fds" file is used by the program to determine the parallel

port and printer type. The choices for the parallel port are '0' for

LPT1 and '1' for LPT2. The choices for printers are "eps" for Epson

compatibles, "hpl" for HP Laserjet+ compatibles and "ibm" for IBM

Proprinter compatibles. The "config.fds" file is ASCII text and can be

modified or created with any standard wordprocessing program. The

default choices in the file included with this package are LPT1 and

Epson compatible.
