A simple method is presented which defines Walsh functions in terms of products of Rademacher functions, but which preserves the ordering of the Walsh functions necessary to retain the notion of increasing number of zero crossings, or sequency.
Gray code, Rademacher functions, sequency, square waves, Walsh functions, zero crossings.
