Synthesis of Digital Filter Structures with Low Roundoff Noise and Coefficient Sensitivity.
Abstract
Optimal synthesis procedures for second-order state-space digital filters have been developed in the sense of minimum output roundoff noise with L2 scaling. It has been demonstrated that these procedures are also nearly optimal for L at infinity scaling. The coefficient sensitivities have been shown to be closely related to the roundoff-noise components, and hence the optimal designs also have low sensitivity properties. The limit-cycle behavior of state-space structures has been investigated for rounding and for magnitude truncation. It was shown that rounding often leads to large antonomous limit cycles; while with magnitude truncation, it is possible to avoid limit cycles altogether. These results are presented in the two papers attached to this report. (Author)
