摘要：
The power density spectrum (PDS) of analog-to-digital (A/D) quantization noise is obtained for an input signal consisting of a sinusoid and colored noise. While this type of quantization noise is often assumed to be uncorrelated or "white," it may not be when the input signal occupies a relatively small number of quantization levels. Equations describing the PDS are derived and presented for combinations of deterministic and random A/D converter inputs. Nonlinear effects arising from A/D converter saturation are not considered.
