K. Prasad, Chikkannan Eswaran, Vempati G. K. Murti · IEEE Transactions on Circuits and Systems · 1987
In contrast to the case of passband. sensitivity, a known criterion for low stopband sensitivity does not exist. In this paper, the relation between the stopband sensitivity of a digital filter and the movement of its transmission zeros with coefficient quantization is investigated.
