bandstop
Bandstop-filter signals
Syntax
Description
filters the input signal y
= bandstop(x
,wpass
)x
using a bandstop filter with a
stopband frequency range specified by the two-element vector
wpass
and expressed in normalized units of
π rad/sample. bandstop
uses a
minimum-order filter with a stopband attenuation of 60 dB and compensates for
the delay introduced by the filter. If x
is a matrix, the
function filters each column independently.
specifies additional options for any of the previous syntaxes using name-value
arguments. You can change the stopband attenuation, the Bandstop Filter Steepness, and the
type of impulse response of the filter.y
= bandstop(___,Name=Value
)
[
also returns the y
,d
] = bandstop(___)digitalFilter
object
d
used to filter the input.
bandstop(___)
with no output arguments plots
the input signal and overlays the filtered signal.
