pydsm.NTFdesign.weighting.q0_weighting

pydsm.NTFdesign.weighting.q0_weighting(P, w, **options)

Compute Q matrix from a noise weighting function or a filter

Parameters

Pint

order of the FIR to be eventually synthesized

wcallable with argument f in [0,1/2] or tuple

• if function: noise weighting function

• if filter definition as zpk or ba tuple: weighting is implicitly provided by the filter

Returns

q0ndarray

the first row of the matrix Q used in the NTF optimization

Other Parameters

quad_optsdictionary, optional

Parameters to be passed to the quad function used internally as an integrator. Allowed options are epsabs, epsrel, limit, points. Do not use other options since they could break the integrator in unexpected ways.

See also

scipy.integrate.quad

For the meaning of the integrator parameters.

Notes

The Q matrix being synthesized has (P+1) times (P+1) entries.

Default values for the options not directly documented in the function call signature can be checked and updated by changing the function default_options attribute.
