Didn't realize I was answering a personal rather than a list email, so I'm forwarding here the piece of information which was supposed to go to the list: While we are on the topic of the book, I have to mention that I found the bug in the Hilbert transformer cutoff formulas 7.42 and 7.43. Tried to merge odd and even orders into a more simple formula and introduced several mistakes. The necessary corrections are (if I didn't do another mistake again ;) ) - the sign in front of each occurence of sn must be flipped - x=(4n+2+(-1)^N)*K(k)/N - the stable poles are given by n<N/2 for N even and n<(N+1)/2 for N odd. I plan to release a bugfix update, but want to wait for possibly more bugs being discovered. Regards, Vadim
