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

nint

the number of optimized zeros to return

osrreal

the oversampling ratio

Returns

zerosndarray of complex

the zeros for the modulator as complex values
