In the mathematical model for the quantization error eq (n), to carry out the analysis, what are the assumptions made about the statistical properties of eq (n)?i. The error eq (n) is uniformly distributed over the range — Δ/2 < eq (n) < Δ/2.ii. The error sequence is a stationary white noise sequence. In other words, the error eq (m) and the error eq (n) for m≠n are uncorrelated.iii. The error sequence {eq (n)} is uncorrelated with the signal sequence x(n).iv. The signal sequence x(n) is zero mean and stationary.
