Digital/Data Communications Digital/Data Communications Problem 1. To determine whether a code (or an encoder)

Problem 1. To determine whether a code (or an encoder) is non-singular, uniquely decod- able, or prefix-free, it is not necessary to consider the whole codebook. Many questions of this type will give only the collection (or list) of codewords that the code uses. Consider the code {0,01}. (a) Is it nonsingular? (b) Is it uniquely decodable? (C) Is it prefix-free
