1. A source emits symbols , in the BCD format with probabilities P(Xi) as given in Table 1, at a rate Rs = 9.6 k-baud (baud=symbol/second). State (i) the information rate and (ii) the data rate of the source. 2. Apply Shannon-Fano coding to the source signal characterized in Table 1. Are there any disadvantages in the resulting code words? 3. What is the original symbol sequence of the Shannon-Fano coded signal 110011110000110101100? 4. What is the data rate of the signal after Shannon-Fanocoding? What compression factor has been achieved? 5. Derive the coding efficiency of both the uncoded BCD signal as well as the Shannon-Fano coded signal.
