IEEE Transactions on Computers, 1974
Any basis function of a generalized Fourier series takes on many values in an interval. In contrast, the binary nature of the basis functions of Walsh-Fourier series (WFS) allows them to be considered self-reciprocal1 except for a finite number of discontinuities. Hence, quotients of linear combinations of Walsh functions may be used to generate series

Diskrete WALSH-Transformationen, schnelle WALSH-Transformationen
1994In diesem Kapitel besprechen wir Zusammenhange, welche fur die numerische Behandlung von WALSH-Transformationen wichtig sind. Wir leiten sog. „schnelle WALSH-Transformationen“ her. Das sind Produktzerlegungen der Transformationsmatrix, welche die Anzahl der Rechenoperationen reduzieren.
