The necessary and sufficient conditions for minimum roundoff noise in second-order state-space digital filters and their optimal synthesis

For second-order state-space digital filters, new expressions for the covariance matrix K and the unit noise matrix W are derived. Using these, the necessary and sufficient conditions for minimum roundoff noise in scaled filters are given in terms of the state parameters. Simple expressions for the...
