The present invention comprises a method and system of sample rate conversion in an efficient way in case that out-of-band noise is present. The presented method and system can be used for reducing (decimating) as well as increasing (interpolating) the sample rate of a time discrete signal. There, the sample rate conversion is achieved by an appropriate combination of decimation and/of interpolation steps with appropriate decimation and/ or interpolation factors for each of the decimation and/of interpolation step. Further, in the present invention, a signal selective filter is incorporated in a flexible way such that the system can be matched to the properties of the incoming signal. Furthermore, sample rate conversion can be split into a coarse and a fine tuning step. |
