A 3-bit digital sensor with an operating range of zero to one volt. Assume that the input voltage is equally likely to be anywhere in the range of zero to one volt. That is, x(t) is a random variable with uniform distribution ranging from 0 to 1. Then the RMS value of the input x is given by the square root of the expected value of the square of x(t), we see that if x(t) is a random variable with uniform distribution ranging from 0 to 1, then the error n(t) in the measurement   equally likely to be anywhere in the range from
