Abstract :
A structure for realization of Nth-order one-dimensional all-pass digital filters containing N multipliers is presented. The Nth-order all-pass transfer function is realized as whole as opposed to realization using a cascade of the first- or second-order filters. The method is simple, and the resulting structure contains N multipliers and N unit delay elements
