Answer the following questions. (a) What is the decoded information bit sequence?  (b) What is the value of the cumulative metric (i.e., Hamming distance) of the final survivor path of the decoding process? (c) Draw the final survivor path of the trellis for the decoding process. Instruction for Part (c): An example of drawing a path in the trellis is shown below.
