The input and output satisfy a difference equation of the form y[n] - (1-alpha) y[n-1] = alpha x[n]

with the corresponding rational system function H(z) = \frac{alpha}{1 - (1-alpha) z^{-1}}

Note that some texts define the system function with a + in the denominator. If you're using that convention, you'll need to negate the feedback tap.

Parameters

(R): Run-time adjustable

Alpha (R)
