  D AT THEIR RESPECTIVE RATES.  THIS REPRESENTS   42 SAMPLES/PROGRAM CYCLE WHERE A CYCLE IS 1.000 SEC
   THE 35 CYCLES OF  42 SAMP/CYC = 1470 WERE THEN SCALED INTO 20 BIT INTEGERS AND PACKED 3 SAMPLES/WOR

   OF EACH PARAMETER  TO ELIMINATE ANY NEGATIVE VALUES. THE BIASED SAMPLE WAS THEN MULTIPLIED BY P(I)
