Forward
FFT
Calculates Fast Fourier Transform on plotted
data. Returns 2 plots  the "real'' and "imaginary" transform
results.


Inverse
FFT
Calculates Inverse FFT. Creates a plot.


Power
Spectrum
Calculates the Power Spectrum of the plotted
data. Creates a single plot of the spectrum.


Apply
Window Function
Applies a weighted function to each sample in the plot.
Creates a plot.


Decimate
By 2
Removes every other sample in the plot and creates
a new plot of the remaining data samples.


DeTrend
Calculates the average value of the data in the plot
and removes that value from each value in the plot.
Creates a new plot of the modified data.


Forward
Difference
Calculates the forward difference of the data in the
plot. Creates a new plot..


Smooth
Data
Applies a first order low pass filter to the data in
the plot and create a new plot of the smoothed data.
The frequency of the low pass filter is defined by the
user.


Data Statistics
Calculates several typical statistical values for the
plotted data and provides the results in a window.
