getOctaveBandwidth

Bandwidth in number of octaves

Syntax

N = getOctaveBandwidth(npFilter)

Description

N = getOctaveBandwidth(npFilter) returns the bandwidth of the notch peak filter, measured in number of octaves.

Examples

Get Octave Bandwidth of Notch Peak Filter

Create a dsp.NotchPeakFilter object in the default configuration.

np = dsp.NotchPeakFilter

np = 
  dsp.NotchPeakFilter with properties:

      Specification: 'Bandwidth and center frequency'
          Bandwidth: 2205
    CenterFrequency: 11025
         SampleRate: 44100

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

getOctaveBandwidth(np)

ans = 0.2881

Visualize the filter response using fvtool.

fvtool(np)

Input Arguments

npFilter — Notch peak filter

dsp.NotchPeakFilter

Notch peak filter whose bandwidth is measured in octaves, specified as a dsp.NotchPeakFilter object.

Output Arguments

N — Number of octaves

scalar

Bandwidth of the filter measured in number of octaves, returned as a scalar.
