Questions

• What is the quality factor of the third-octave filters whose bandwidth is given in Equation (6)?
• What is the bandwidth of an ERB filter centered at 1 kHz? What is the quality factor of this filter?
• Centered at 1 kHz, what is the difference between the bandwidth of an ERB filter and a third-octave filter, expressed as a percentage of center frequency?
• Repeat the previous question for a filter centered at 250 Hz.
