a₁ A source has an alphabet with probabilities (0.1, 0.23, 0.25, 0.05, 0.15, 0.22). 1. Find the entropy of this source. 2. Compare this entropy with the entropy of a uniformly distributed source with the same alphabet. 3. Compute the compression ratio and the coding efficiency. a₂ a3 a4 26 a5 Alphabet Probabilities 0.1 0.23 0.25 0.05 0.15 0.22 Equal Probabilities 1/6 1/6 1/6 1/6 1/6 1/6 Code 1 Code 2
