Question: A source emits three equiprobable messages randomly and independently. 1 . Find the source entropy. 2 . Find a compact ternary code, the average length

A source emits three equiprobable messages randomly and
independently.
1. Find the source entropy.
2. Find a compact ternary code, the average length of
the code word, the code efficiency and the
redundancy.
3. Repeat part (2) for a binary code.
4. To improve the efficiency of a binary code, we now
code the second extension of the source. Find a
compact binary code, the average length of the code
word,
the code efficiency and the redundancy.
