Chien‐Cheng Tseng, Su‐Ling Lee · 2019
In this paper, the design of graph filter using spectral transformation and window method is presented. First, the specification of graph filter is converted to the one of digital filter using spectral transformation. Then, the window method is employed to design the digital filter with converted specification. Next, the binomial series expansion is used to obtain the coefficients of the graph filter from those of digital filter. Finally, the numerical design examples are demonstrated to show the effectiveness of the proposed graph filter design method.
