A simple method of Walsh spectra multiplication
K. R. PALANISAMY, V. P. Arunachalam · International Journal of Control · 1984
The paper presents a new easy method to obtain the product of the Walsh spectra of two functions. The method makes use of both the spectra of Walsh and block-pulse functions (b.p.f.s). The proposed method can be easily implemented with a digital computer. It will be very useful in the analysis and optimal control of time varying systems via Walsh functions.
