Abstract:
A sampling rate converter includes a chain of identical cells connected in series. An input of a first cell of the chain receives input digital sampling values according to an input frequency. An output of the first cell then delivers output digital sampling values according to an output frequency. The input and output digital sampling values correspond to identical respective reconstruction curves, and the output frequency may be greater than or less than the input frequency. Each cell includes a storage element, two multipliers and two adders.
