Question

The performance of the DPCM-coder improves as the

• A. Sample-to-sample correlation of the input increases.
• B. input dynamic range increases.
• C. input probability density becomes more and more Gaussian.
• D. input power density tends to be white.

Answer 1

The correct option is A Sample-to-sample correlation of the input increases.

The performance of the DPCM-system improves as the correlation between the adjacent samples increases.
