The Walsh-Hadamard transform is a non-sinusoidal, orthogonal transformation technique that decomposes a signal into a set of basis functions. These basis functions are Walsh functions, which are rectangular or square waves with values of +1 or –1. Walsh-Hadamard transforms are also known as Hada...

Terry Ritter Most introductions to Walsh-Hadamard transforms are heavily mathematical and difficult to relate to practice. But the transformation process itself is just arithmetic, and has an easily-comprehended structure which could be widely understood. The result is often thought of as "a poor-man...
The WHT is a suboptimal, non-sinusoidal, orthogonal transformation that decomposes a signal into a set of orthogonal, rectangular waveforms called Walsh functions. The transformation has no multipliers and is real because the amplitude of Walsh (or Hadamard) functions has only two values, +1 or ...
