...INTRODUCTION Walsh functions are defined as a complete set of normal orthogonal functions over a given finite interval and takes on the values +1 or -1[1,2] over a finite domain where the value becomes zero, and the number of zero crossings within specified domain gives the order of the Walsh Function....
