... Therefore we cyclically shift the array of c k ’s, to bring everything to positive lag. (This corresponds to introducing a time-delay into the filter.) Do this by copying the c k ’s into a new array ... particularly about the case in which you have chosen to do such filtering in the time domain. Before continuing, we hope youwill reconsider this choice. Remember how convenient it is to fil...
