Consider the convolutional encoder shown in Fig. 1.23.

a) Draw the trellis corresponding to four information digits and m = 1 dummy zero.

b) Find the number of codewords M represented by the trellis in Problem 1.29(a).

c) Use the Viterbi algorithm to decode when the sequence r = 11 01 10 10 01 is received over a BSC with 0
