Control System Question

[Thomas D. Dean]

I am trying to understand a control system

y(n) = y(n-1) + (1/F1 + 1/F2)*x(n) + (1/F1 - 1/F2)*x(n-1)

where F1=2^6 and F2=2^10.  Which is really an IIR filter.

I have an implementation of this in a uProcessor, controlling a DAC in 
response to counted inputs.  I can monitor these signals with a digital 
scope.

I am trying to understand it with the aim of improvement.

How do I implement this with control 2.2.4?
