TITLE:

A Test-Waveform View of the Quadratic Design of FIR Filters

ABSTRACT:

This paper suggests that when a test system in which an FIR filter is embedded is driven by a random-process input with a suitably chosen power spectrum, the system output power becomes a suitable quantity for constraint or minimization in a numerical optimization of the filter coefficients. Each such combination of test confuguration and test-input spectrum eventually corresponds to one constraint (or the objective function) in a quadratic optimization, which is here cast into the form of a semidefinite program for numerical optimization. Illustrated here by the design of a simple lowpass FIR filter, this method can be generalized to handle many types of filters and constraints.
