The

**typical set**is the set of sequences whose probability is near to the entropy of their source distribution and is a consequence of the asymptotic equipartition property.

[*This does not make sense. How can a set be a consequence of anything? A set is not a proposition.*]

If a sequence is drawn from an i.i.d. distribution then the typical set, is defined as those sequences which satisfy:

It has the following properties if is sufficiently large:

- The probability of a sequence from being drawn from
