BandstopFilter

BandstopFilter[data, {ω1, ω2}] applies a bandstop filter with cutoff frequencies ω1 and ω2 to an array of data.

BandstopFilter[data, {{ω, q}}] uses center frequency ω and quality factor q.

BandstopFilter[data, spec, n] uses a filter kernel of length n.

Examples

Apply bandstop filter:

data = Table[Sin[2 Pi 0.1 t] + Sin[2 Pi 0.4 t], {t, 100}];
BandstopFilter[data, {0.3, 0.5}]
