5. Eight letters {A, B, C, D, E, F,G,H} appear in a 100 letter length message with the following frequencies: 22, 6, 13, 19, 2, 9, 25, 4. (a) Use Huffman tree to design an optimal binary prefix code for the letters. (b) What is the average bit length of the message after apply codes designed in (a) to the message? [20 marks]
Design a Shannon-Fano code and sketch the corresponding coding tree where the alphabet is {a,b,c,d,e,f} with corresponding probabilities {0.5, 0.1, 0.05, 0.05, 0.25, 0.25}
An alphabet contains symbols A, B, C, D, E, F. The frequencies of the symbols are 35%, 20%, 15%, 15%, 8%, and 7%, respectively. We know that the Huffman algorithm always outputs an optimal prefix code. However, this code is not always unique (obviously we can, e.g., switch 0’s and 1’s and get a different code - but, for some inputs, there are two optimal prefix codes that are more substantially different). For the purposes of this exercise, we consider...
4. Consider the given seven symbols with probabilities as {A, B, C, D, E, F, G} = {0.25, 0.20, 0.18, 0.15, 0.12, 0.06, 0.04}. Use Huffman coding to determine coding bits, entropy and average bits per symbol.
We have the symbols A, B, C, D, E, F, G, H with frequencies 1, 1, 2, 4, 8, 16, 32, 64. Show the Huffman tree and Huffman code for the symbols. How much compression does a 1000 digit file use when using this Huffman code based on an 8-bit ASCII code (ie, ISO 8859-1)?
