Abstract
The structure of a digital filter is provided through exponentiation of a polyphase digital filter. This exponentiation may be accomplished by determining an expression for the polyphase digital filter in terms of its polyphase components, and raising the expression for the polyphase digital filter to a power. The polyphase components are then arranged in a structure based on this exponentiated expression.
