1. A method for determining a digital filter structure, the method comprising: obtaining a transfer function of a digital filter in the form of one or more filter components including an annihilating component, a minimum phase component, a non-minimum phase component, and a symmetric component; and for each of the one or more filter components, representing 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.
