CWT filter bank quality factor
returns the quality factor for the wavelet bandpass filters in
qf
= qfactor(fb
)fb
. The quality factor is the ratio of the 3-dB bandwidth
to the center frequency, where the center frequency is the geometric mean of the
bandwidth frequencies. The larger the quality factor, the more frequency localized
the wavelet. For reference, a half-band filter has a quality factor of
sqrt(2)
.
