3. An alphabet contains symbols which are transmitted in the BCD format with probabilities P(X) as given in Table 1, at a rate Rs = 28.8 kbaud (baud-symbol/second). a. State (i) the information rate (R = H Rs) and (ii) the data rate (number of bits. Rs) of the source. b. Apply Huffman coding to the source signal characterized in Table 1. c. What is the original symbol sequence of the Huffman coded signal 00010110010011010101001? d. What is the data rate of the signal after Huffman coding? What compression factor has been achieved? e. Derive the coding efficiency of (i) the uncoded BCD signal and (ii) the Huffman coded signal. (CE = information rate/data rate) Table 1 P(X₁) BCD word 0.15 000 0.08 001 0.12 010 0.17 011 0.42 100 0.06 101 XABCDEF
