WebbThe Shannon entropy represents a lower bound on the average number of bits needed to represent the information symbols without losing any information. In other words, the code should be uniquely decodable. The examples you gave do not constitute a uniquely-decodable code. For example, how do you decode 010? Is it 0, 1, 0 or 0, 10?
