This problem is about designing LSI graph filters using least squares. An LSI graph filter can be defined through its frequency response h ( ? `) at its distinct frequencies ? `, for ` = 0 , 1, . . . , N ? 1. In the weight matrix based DSP G framework, an LSI graph filter is a polynomial (in the weight matrix) of degree M. To construct an LSI filter with frequency response h ( ? `) = b `, one need to solve a system of N linear equations with M + 1 unknowns h 0, h 1, . . . , h M
In general, N > M + 1, and therefore, the system of linear equations is overdetermined
and does not have a solution. In this case, an approximate solution can be found in the
least-squares sense.
Design the filters with the following specifications using least squares for the graph shown in
Figure 10.7.
(a) A low-pass filter of order two that passes only the smallest two frequencies.
(b) A high-pass filter of order two that passes only the largest two frequencies.
(c) A band-pass filter of order two that passes only two frequency components ?2 and ?3.
