Details
filterCoef is a generic function to extract the coefficients of
periodic filters. Argument convention can be used to force a
particular convention for the signs. The description here is for the
methods defined in this package.
If convention is missing, the coefficient matrix is returned as
stored in the object. Otherwise, if convention is one of the
strings "BJ", "--" or "-", the coefficients
returned have the opposite sign of those in the auxilliary polynomial
(Box-Jenkins' convention). If convention is one of "SP",
"++" or "+", the coefficients are as in the auxilliary
polynomial (convention used in signal processing).
