摘要：
Idle tones and noise modulation in higher-order sigma-delta modulators (SDMs) can be eliminated using single-bit dither signals, with no additional reduction in dynamic range compared to multilevel dither signals. Unlike multilevel dither, single-bit dither is easily implemented in sigma-delta analogue-to-digital converters (ADCs).
