1 - SECOND-ORDER ACTIVE FILTERS

Figure 1-3 - Location of the poles of a second-order system in the complex frequency plane. It is of interest to us to plot the locus of the poles, p1 and p2, as Q is varied from 0 to ∞. The resulting plot is called a root locus plot and is shown in Fig. 1-4. There are two loci on this plot, one corresponding to p1 and the other to p2. At Q=0 ...
