thus, e is in the range −0.5 to 0.5 in our example. When the input signal U varies with time,

the quantization error forms an error sequence e(nT), where T is the sampling interval (T =
1/f ) and n is a positive integer, n = 0, 1, 2, and so on. The error sequence plays an important

role in oversampling ADCs. We will see that processing the error sequence is the key to
increasing the number
