Open Live Script

Create a dsp.NotchPeakFilter object with the NormalizedFrequency property set to true.

np = dsp.NotchPeakFilter(NormalizedFrequency=true)
np = 
  dsp.NotchPeakFilter with properties:

          Specification: 'Bandwidth and center frequency'
              Bandwidth: 0.1000
        CenterFrequency: 0.5000
    NormalizedFrequency: true

Determine the octave bandwidth of the filter using the getOctaveBandwidth function.

getOctaveBandwidth(np)
ans = 
0.2881

Visualize the filter response using filterAnalyzer.

filterAnalyzer(np)
