Explore: Walsh Functions

Walsh functions form a complete orthogonal set of functions that can be used to represent any discrete function—just like trigonometric functions can

2. It decomposes an arbitrary input vector into a superposition of Walsh functions. The transform is named for the French mathematician Jacques Hadamard

a Walsh matrix is sequency-ordered. Confusingly, different sources refer to either matrix as the Walsh matrix. The Walsh matrix (and Walsh functions) are

coefficients of a decomposition into linear functions (Walsh functions), analogous to the decomposition of real-valued functions into harmonics by the Fourier transform

based on Walsh functions. Both layers are of similar nature: they constitute a "1-out-of-N" FEC code. For the first layer the orthogonal functions are (co)sine

orthogonality of both radial and angular parts. Walsh functions and Haar wavelets are examples of orthogonal functions with discrete ranges. Legendre and Chebyshev

(binary) addition and reflects the discontinuous nature of Walsh functions. For a function f {\displaystyle f} defined on [0,1), the first pointwise dyadic
