Discrete-time, parallel structure filter
dfilt.parallel in Signal Processing Toolbox™ documentation.
hd = dfilt.parallel(hd1,hd2,...) returns
a discrete-time filter object
hd, which is a structure
of two or more
dfilt filter objects,
and so on arranged in parallel.
You can also use the standard notation to combine filters into a parallel structure.
In this syntax,
and so on can be a mix of
dfilt objects and
hd2, and so on can
be fixed-point filters. All filters in the parallel structure must
be the same arithmetic format — double, single, or fixed.
the filter returned, inherits the format of the individual filters.
