5.1. A binary asymmetric channel is similar to a BSC, except that the probability of error when 0 is sent is a, and the probability of error when 1 is sent is b, where a=b. Write down the matrix for this channel. 5.2. A ternary symmetric channel is a channel for which the input set I and output set J are both {0,1,2}, and the probability that a symbol i becomes j=i is x. Write down the matrix for this channel
