pydsm.NTFdesign.psychoacoustic.dunn_optzeros_cplx(order, osr)

Helper function for synthesising psychoacoustically optimal modulators.

Returns the complex zeros which minimize the in-band noise power of a delta-sigma modulator’s NTF after weighting by the F-weighting. The signal bandwidth is 22.05 kHz.

Parameters:

n : int

the number of optimized zeros to return

osr : real

the oversampling ratio

Returns:

zeros : ndarray of complex

the zeros for the modulator as complex values
