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
