Figure 3−31. Triangular Dither Statistics
Figure 3−32 presents plots of the autocorrelation and channel-to-channel correlation properties of the dither data
stream when configured as quadratic distributed noise. Figure 3−32(a) is the circular autocorrelation of 16K samples
of dither data collected from the TAS3103. The audio signal level was set to zero and the dither data stream was
inserted at the LSB+1 level of the output word. The autocorrelation contains a single line of value 16,000 at the point
of correlation and random noise terms of approximately ±300 counts in value. The value 16,000 agrees with the
