Let the conditions be as in 1 and 3 except for the fact that four separated condensers are used. Then yl/M B' (a + ico)'* (52) The solution is most readily obtained by selecting every fourth term in the series obtained in 1. s{t) = Be-"\BH'/3l + B't'/ll + = f5c-«' (sinh Bt - sin Bt), â ) (53) This indicates a condition of instability when B â a, agreeing with the result deducible from the admittance diagram. 6. Let the conditions be as in 5 except that there is a reversal. Then Y = - B' (a + â¢z'co)'* (54) The solution is most readily obtained by changing the sign of every other term in the series obtained in 5. s(l) = Be-"\- BH'/Sl + B'tyjl - ⢠⢠â¢)⢠(55). w-plane: Fig. 6âIllustrating Example 6, with two values for Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original American Telephone and Telegraph Company.
