D AT THEIR RESPECTIVE RATES. THIS REPRESENTS 60 SAMPLES/PROGRAM CYCLE WHERE A CYCLE IS 1.000 SEC
THE 25 CYCLES OF 60 SAMP/CYC = 1500 WERE THEN SCALED INTO 20 BIT INTEGERS AND PACKED 3 SAMPLES/WOR
D INTO 500 60 BIT PACKED WORDS --METHOD OF SCALING-- A BIAS AD(I) WAS ADDED TO EACH SAMPLE
OF EACH PARAMETER TO ELIMINATE ANY NEGATIVE VALUES. THE BIASED SAMPLE WAS THEN MULTIPLIED BY P(I)
TO INSURE THE PROPER NUMBER OF DECIMAL PLACES WERE SAVED. THE PACKED RECORD MAY BE UNPACKED BY RIGH
