METHOD FOR REGENERATING SOURCE SIGNAL IN DELTA MODULATION AND DELTA MODULATOR IMPLEMENTING IT Russian patent published in 1999 - IPC

FIELD: communications and computer engineering; data transmission with any type of delta modulation. SUBSTANCE: method involves reduction of both distorted over-transconductance and quantization noise when generating only one approximating voltage for any type of delta modulation. Delta modulator has arriving pulse polarity identifier, arithmetic-and-logic unit, clock generator, polarity-reversing digital-to-analog converter, integrator, low-frequency filter, and data reprocessing and re-coding unit. EFFECT: improved accuracy of source signal regeneration. 2 cl, 25 dwg, 6 tbl
