  • Look-up table delta-sigma conversion
    Patent number: 7190288
    Abstract: Signal conversion is implemented employing a memory system operating as a look-up table that stores a plurality of sets of output samples associated with each of a plurality of respective input samples. The look-up table thus can generate a corresponding set of output samples in response to a given input sample, thereby emulating desired digital upsampling and delta-sigma modulation. The output samples can be aggregated, such as by multiplexing, to provide an output data stream at a desired sample rate.
    Type: Grant

    Date of Patent: March 13, 2007
    Assignee: Northrop Grumman Corp.

  • Conversion employing delta-sigma modulation
    Patent number: 6873280
    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.
