摘要： The present invention teaches a data processing system capable of performing a sampling frequency conversion. The data processing system includes a data receiving means for receiving a plurality of input data sampled at a first frequency. The data processing system further includes a discrete transforming means for performing a discrete transform on the input data at the first sampled frequency for transforming the input data to a discrete function in a second-variable-domain at the first sampling frequency. The data processing system further includes a convoluted inverse transforming means for inversely transforming the discrete function in a second-variable-domain back to the time domain at a second sampling frequency for converting the input data to a set corresponding data sampled at the second sampling frequency.
