Problem 3: What three ASCII letters (bytes) are encoded by the following 4B/5B pattern? (Case sensitive)
010110101001110101010111111110
Given 4B5B encoded data is
01011 01010 01110 10101 01111 11110
The 4B5B encoding table is given below.
After decoding (using the reverse mapping i.e. 5 bits to 4 bits) we get,
0101 0100 0110 0011 0111 0000
Now representing the decoded bits as Bytes we get,
01010100 01100011 01110000
Thus representing as hex values we get,
0x54 0x63 0x70
The ASCII table is given below
Now using this ASCII table we get the decoded ASCII characters as
T c p
