  • 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
    Filed: June 27, 2003
    Date of Patent: March 13, 2007
    Assignee: Northrop Grumman Corp.
    Inventors: Ian Stuart Robinson, Jeffrey Mark Hinrichs, Jasmine Upendra Patel, Paul Charles MacFalda, Reza Dehmohseni, Frederic J. Harris, Kenneth Weber
