Webb• The Shannon-Fano code taken with respect to a universal measure is an instance of a lossless universal code for data compression. Other important instances of universal codes were discovered in [5, 6, 7]. These other codes do not necessarily induce a universal measure due to the strict Kraft inequality. WebbIn our example it would look like this: Here, s1=d, s2=b, s3=a, s4=c. Step 2 Determine code length The code length of each codeword using the formula we will continue to seek: … WebbUnfortunately, Shannon–Fano does not always produce optimal prefix codes; the set of probabilities {0.35, 0.17, 0.17, 0.16, 0.15} is an example of one that will be assigned non- optimal codes by Shannon–Fano coding. … can guinea pigs have marshmallows
