摘要: This paper is concerned with the use of 1-bit delayed encoding in operation a continuously variable slope delta modulator (CVSDM). Delayed realized as time-adaptation process capble anticipating slope-overload bursts by overriding ordinary CVSDM. Practical realization CVSDM version shows that its offers up to 5 dB S/N improvement for medium sampling rates no major increase encoder's circuit complexity.
