Let f be a sufficiently expanding C 2 circle map. We prove that a certain Markov approximation scheme based on a partition of S 1 into 2 N equal intervals produces a probability measure whose total variation norm distance from the exact absolutely continuous invariant measure is bounded by CN2-N; C is a constant depending only on the map f.
