Sumber artikel:Jurnal. Halaman: 127-136 Walsh transform is similar to Fourier transform. In fourier transform a periodic signal can be broken down into sine and cosine wave at fundamental frequency and higher frequency (harmonic frequencies). In walsh transform a periodic signal can be decomposed into square wave at fundamental frequency and higher frequency (harmonic frequencies). Computation in Walsh transform can be minimized into faster computation and becomes fast Walsh transform. A variant of Walsh transform is hadamard transform which is Walsh transform arranged in natural order (known as sequency order).
