The W Transforms are widely used in digital signal processing. This paper proposes a novel approach to compute
Discrete W Transforms via computation of the first-order moments without multiplications. A scalable and efficient
systolic array is designed to implement this approach. Compared with the other existing methods, the proposed
algorithms is simpler and more applicable.
