In digital television, what does a coding rate of 3/4 mean?
Pick an answer to check it.
Answer: A. 25% of the data sent is forward error correction data
A coding rate of 3/4 means 3 of every 4 bits are user data and 1 of every 4 bits is forward error correction. So 25% of the data sent is FEC.
Tip: 3/4 data, 1/4 (25%) error correction.
