Abstract
Signal conversion of an input signal can be achieved by processing portions of the signal through plural parallel paths, which collectively approximate a desired infinite impulse response (IIR) filter, either alone or implemented with other signal processing functions. In one aspect, each of the paths can perform filtering, noise-shaping and/or quantization on a respective portion of the input signal to provide a corresponding representation of the respective portion of the input signal, for example, a coarser representation at a higher data rate. The corresponding representations from the parallel paths can be aggregated and further processed in a desired manner, such as conversion to an analog signal.
