Digital Filtering Using The HPC

A second order section such as the above can be realized in a number of ways; the one of concern here is the socalled 1-D form (see Reference 3). The second order 1-D form is shown in Figure 2. Based on this figure, we can obtain the following equations: m(k) e x(k) b B1 c m(k b 1) b B2 c m(k b 2) y(k) e A0 c m(k) a A1 c m(k b 1) a A2 c m(k b 2) Define T1 e bB1 c m(k b 1) b B2 c m(k b 2), T2 e A1 c m(k b 1) a A2 c m(k b 2) TL/DD/9247–2
