Detailed Description
single pole IIR filter with float input, float output
The input and output satisfy a difference equation of the form \f{ y[n] - (1-alpha) y[n-1] = alpha x[n] \f}
with the corresponding rational system function \f{ H(z) = \frac{alpha}{1 - (1-alpha) z^{-1}} \f}
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.
