There is a coding table like this:
- 0 for A
- 01 for B
- 011 for C
- 1110 for D.
I know this coding is uniquely decodable but not instantaneous since it's not a prefix code. For recognizing whether 0111 will become AD or something like B.. or C... decoder has to wait. If the next symbol is a 0 then it must be an AD. So is 4 number of symbol delay in this decoder?
