> y(n) = k2*x(n) + k1*(1+k2)*x(n1) + x(n2)  k1*(1+k2)*y(n1)  k2*y(n2)
Hey thanks. That answers a ton for me. I guess the last thing I had on my mind was in regards to n.
Since X would be a trace containing an array of samples, x[0] would contain the first sample. In the algorithm, there is a point where it is asking for x[n1] and x[n2]. In the case that n would equal 0, the first part (n1) would try to pull a value from the 1 element in the array. How would I work around that for the first few elements of the array?
