ABSTRACT
The statement HOLD ON stipulates that all succeeding curves be plotted on the same axes as were used for the preceding graph; thus we superimpose all the individual (dashed line) component curves and also the final composite (solid heavy line) curve. Figure 9-5 shows the results of the above calculations. (Recall that we have "left out" the steady-state gain of -50.46 db; thus our curves are all referenced to the 0-db line.) As in our earlier example, we again see that the higher-frequency resonances are suppressed, even though they "individually" are lightly damped with
Ani Qol (iw) + An2Qoz(iw) + · · · + AnnQon(iw) = CnaQ;a(iw) + CnbQ;b(iw) + · · · From linear algebra we know that the unknowns can be found by first obtaining the inverse of the matrix of A coefficients and then matrix multiplying this by the column vector of C coefficients that remains on the right-hand side when all Q;'s other than the selected Q;k are set to zero.
