Digital filter
Use designfilt
in
the form d = designfilt(resp,Name,Value)
to design
a digital filter, d
, with response type resp
.
Specify the filter further using a set of Name,Value
pairs.
Use designfilt
in
the form designfilt(d)
to edit an existing filter, d
.
This is the only way to edit a digitalFilter
object.
Its properties are otherwise read-only.
Use filter
in
the form dataOut = filter(d,dataIn)
to filter a
signal with a digitalFilter
, d
.
The input can be a double- or single-precision vector. It can also
be a matrix with as many columns as there are input channels.
Use fvtool
to
visualize a digitalFilter
, d
.
The following functions take digitalFilter
objects
as input.
