An improved L/sub 2/-sensitivity measure for linear state-space digital systems is presented.
It gives a more precise evaluation of the transfer function deviation/spl Delta/H (z) between …

One important criterion for a model's utility is its scope, the ability to predict a wide range of
results. Scope is often difficult to ascertain without extensive data fitting. For example, JE …

The convergence of previously described output error identification procedures is examined.
The convergence analysis uses the eigeninformation of the parameter correlation matrix …

The authors investigate the usefulness of structures with high parameter sensitivities for the
purpose of increasing the convergence rate of parameter identification algorithms. In …

In this paper, we introduce the notion of entropy in the context of digital filter sensitivity. In
particular, we discuss its application in several FIR filter structures. We compare the …

This paper presents our work in minimizing the required space on a field programmable
gate array (FPGA) for IIR digital filters. The method does not alter the filter frequency …

The effects of a chosen system structure on the identification of its parameters are
considered. In particular, convergence rates are compared for the parameters of three state …

The scaling factor in a direct form II infinite impulse response (IIR) digital filter depends on
only the system poles, not its zeros. Adding pole-zero cancellation pairs changes the scaling …

Finite wordlength effects in digital filters and controllers have been explored over the last
three decades. Much of the work has originated from the digital signal processing …
