1. A method to determine a digital filter structure, the method comprising: obtaining, by a processor, a transfer function of a digital filter, wherein the digital filter includes one or more filter components including an annihilating component, a minimum phase component, a non-minimum phase component, and a symmetric component; creating a representation of the digital filter, wherein the representation represents each of the filter components as a set of interconnected notch filters, wherein each set of notch filters includes at least one of a first notch filter having a half-lattice structure, and a second notch filter having a full lattice structure; and storing the representation in a memory.
