The 5th-order modulator outperforms the 3rd-order one [7] by placing the additional NTF zeros in or close to these bands. Unfortunately, this can not be achieved by classical modulator design tools. The key concept of the proposed method is to optimize the placement of NTF out-of-band non-conjugate zeros in

Webopt A ﬂag used to request optimized NTF zeros. opt=0puts all NTF zeros at band-center. opt=1optimizes the NTF zeros according to the high-OSR limit. opt=2puts at least one zero at band-center, but optimizes the rest. opt=3uses the Optimization toolbox to optimize the zeros.
