cupyx.scipy.signal.band_stop_obj#
- cupyx.scipy.signal.band_stop_obj(wp, ind, passb, stopb, gpass, gstop, type)[source]#
Band Stop Objective Function for order minimization.
Returns the non-integer order for an analog band stop filter.
- Parameters:
wp (scalar) – Edge of passband passb.
ind (int, {0, 1}) – Index specifying which passb edge to vary (0 or 1).
passb (ndarray) – Two element sequence of fixed passband edges.
stopb (ndarray) – Two element sequence of fixed stopband edges.
gstop (float) – Amount of attenuation in stopband in dB.
gpass (float) – Amount of ripple in the passband in dB.
type ({'butter', 'cheby', 'ellip'}) – Type of filter.
- Returns:
n – Filter order (possibly non-integer).
- Return type:
scalar
