Abstract
A data processing circuit includes a digital data source having an output carrying a sequence of digital signals. A pre-filter is coupled to the output of the digital data source. The pre-filter has a first output that carries a second sequence of digital signals and a second output that carries a third sequence of digital signals. The second sequence of digital signals is time shifted relative to the third sequence of digital signals. The circuit also includes an interpolation circuit with a first input coupled to the first output of the pre-filter and a second input coupled to the second output of the pre-filter.
