The transfer function (in Z-transform) of a first order low-pass filter is TF = kz^-1/(1-(1-k)z^-1) in which 1/k is the time constant. Using a time constant of 2^n, TF = (1/2^n)/(z-(2^n-1)/2^n).
Let x(k) and y(k) be the input and the output.
y(z)/x(z) = (1/2^n)/(z-(2^n-1)/2^n)
Take the inverse Z-transform
When n = 3
