1. The statistics do not change with time.
2. It is a sequence of uncorrelated random variables.
3. It is uncorrelated with the quantizer input x(n).
4. The probability density function is uniformly distributed over the range of values of quantization error. Which of the above statements are correct?

5.
Which of the following statements is/are correct?
1. A system is said to be Finite Impulse Response (FIR), if the output samples of the system depend only on the present input and a finite number of past or previous input samples.
2. If the output of a system y(n) depends only on the present input and past inputs, but not on past outputs, then it is called a non-recursive system.
3. If the output of a system y(n) depends only on the present input and past inputs, but not on past outputs, then it is called a recursive system.
