28 5 月 Since W is additionally an orthogonal matrix W T = n W ? 1

in which X 's the discrete Walsh transform out-of x and you may W is an enthusiastic letter ? n symmetrical matrix to ensure W T = W .

The partnership between your WAL, CAL, and you may SAL indicator, and you can sequency resemble the connection within distinct Fourier list and you can frequency

The career of factor n can be a bit haphazard since it can happen from the transpose or perhaps the inverse transpose.

An excellent Walsh changes regarding letter real viewpoints enjoys n genuine values within its change.
