Question 1 - On Signaling Encoding (12 points) In the 4b/5b encoding (Table 1), only two of the 5-bit codes used end in two 0's. How many possible 5-bit sequences are there (used by the existing code or not) that meet the following stronger restriction: - Has at most one leading 0 , and - Has at most one trailing 0 a) (9 points) Please write all the 5-bit sequences that meet this stronger restriction. Table 14b/5b table b) (3 points) Could all 4-bit sequences be mapped to such 5-bit sequences. Please explain
