Determine the SNR for a quadrature delta-sigma modulator using simulations. The modulator is described by a noise transfer function (ntf) and the number of quantizer levels (nlev). The ntf/stf may be given in ABCD form. The band of interest is defined by the oversampling ratio (R) and the center frequency (f0).
