Abstract :
In this paper we consider quantized frame expansions and pair frames. Especially one method of quantization called Sigma Delta algorithm is studied, also we study pair frames and we obtain some properties of them. Moreover by using pair frames, duals and controlled frames, we get some upper bounds for the error obtained in Sigma Delta algorithm.
