Let's take your suggestion for now. I am trying to implement it in MATLAB, what I'm doing is evaluating the transfer function and I got this: H(z) = alpha/[1+(alpha-1)*z^-1] Is it correct? Then I chose a value for alpha = 0.1 finally I am filtering using this commad: b = [0.1]; a = [1 -0.9]; err = filter(b,a,error_sig); where error_sig is the output of the error detector. Please confirm my work if it's correct.
