Lattice filter transfer function
Webz-transfer function of order n, there exist 22'~-1 different ways of connecting lattice sections in terms of circuit implementation. Among them, we identify two uniform-structured lattice realizations with the orthogonal expansion coefficients as the tap parameters. The two lattice structures will be connected in a cascade WebTo develop the all-pass transfer function from a low-pass response, replace A 0 with the conjugate complex denominator. ... In addition, a particular choice of the all-pass implementation gives rise to certain well-known WDFs …

WebThe lattice filter is designed with two cascaded steps, where each step used two cleanup filters. The first and second cascaded step are designed with three- and two-stage lattice filter, respectively. To achieve 800 GHz channel spacing, first cascaded step is designed for 2×800 GHz FSR and second cascaded step is designed for 4×800 GHz FSR.
