Abstract
An analogue to digital or digital to analogue data converter for converting between a first digital signal at a first sampling rate f and a first analogue signal comprises a first conversion stage for converting an input signal into an intermediate digital signal at a second sampling rate f which is greater than the first over-sampling rate f ; a processing stage for performing digital signal processing on the intermediate digital signal to generate a processed intermediate digital signal and a second conversion stage for converting the processed intermediate digital signal into an output signal wherein the input and output signals comprise the first analogue signal and the first digital signal or vice versa depending on whether the data converter is performing analogue to digital or digital to analogue conversion.
