Design of frequency-domain experiments for discrete-valued factors

摘要

We provide theoretical justification for the use of an existing technique for studying binary-valued inputs in the Fourier frequency domain. Extending this work, we propose two methods for handling general discrete-valued factors, and illustrate their use. The two methods are found to have complementary applicability. When combined with previously developed techniques, they generalize the frequency- domain approach to encompass discrete as well as continuous inputs.
