         ' This GUI illustrates random signal concepts.    ' 
         ' It plots the sum of random signals and their    '   
         ' histogram. You can edit values for number of    '
         ' signals, the signal length and number of bins.  '
         ' You can also select the noise distribution.     '
         '                                                 '
         ' The mean, STD and variance of the sum is shown  '
         ' in the signal measures area.                    '
         ' All plots and values for the signal measures    '
         ' are updated as edits are made.                  '

         ' of a sum of random signals tends to a Gaussian  '  
         ' (the central limit theorem).                    '];
