Abstract
In the preceding chapters, we have encountered both continuous and discrete frames the latter are more traditional, but in fact the two are necessarily linked. Suppose one is dealing with a continuous frame, of rank one for simplicity. When it comes to numerical calculation, the integral has to be discretized, so that in effect one always restricts oneself to a discrete subset of X.
