Open Live Script

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)

Figure Figure 1: Magnitude Response (dB) contains an axes object. The axes object with title Magnitude Response (dB), xlabel Frequency (kHz), ylabel Magnitude (dB) contains an object of type line.

Input Arguments
