band_stop_obj

scipy.signal.band_stop_obj(wp, ind, passb, stopb, gpass, gstop, type)

Band Stop Objective Function for order minimization.

Returns the non-integer order for an analog band stop filter.

Parameters:

wpscalar

Edge of passband passb.

indint, {0, 1}

Index specifying which passb edge to vary (0 or 1).

passbndarray

Two element sequence of fixed passband edges.

stopbndarray

Two element sequence of fixed stopband edges.

gstopfloat

Amount of attenuation in stopband in dB.

gpassfloat

Amount of ripple in the passband in dB.

type{‘butter’, ‘cheby’, ‘ellip’}

Type of filter.

Returns:

nscalar

Filter order (possibly non-integer).
