System object: dsp.ParametricEQFilter
Convert bandwidth to quality factor
dsp.ParametricEQFilter object will be
removed in a future release. Existing instances of the object continue to run. For
new code, use the
from Audio Toolbox™ instead.
Q = getQualityFactor(H)
Q = getQualityFactor(H) returns the quality factor (Q factor) for
the parametric equalizer filter. The Q factor is defined as the center frequency divided
by the bandwidth.
