ABSTRACT:
Extending an existing architecture for delta-sigma conversion of vector inputs, we suggest spectrally shaping quantization noise jointly in temporal and spatial frequency domains with delta-sigma modulation, and we examine the application of the idea to wide-band antenna or acoustic arrays and to halftoning of video imagery.
