Ntf out of band gain
WebNTF out-of-band gain also increases. The highest out-of-band gain possible for the 6-th order NTF does not compensate the higher order of an 8-th order NTF in terms of SNDR. This is a general observation. Finally, as the number of fractional bits increases, there is no significant impact on the maximum possible NTF out-of-band gain. The ...
