Hi All,


I'm new to SigmaStudio and I'm trying to implement the following algorithm (comb filter).  I have no problems with y(n) = x(n)  –  x(n - Nf) but when I try to add the 'alpha' term I get an error 'illegal feedback'.  Sampling frequency is 48k and Nf is 800.  Alpha must be less than 1.


y(n) = x(n)  –  x(n - Nf)  + alpha*y(n – Nf)


Any input would be appreciated.


Best regards,
