Stability Theory » Exercise - 262. The Nyquist plot intersects the real axis at –a = -0.02, the gain margin is : (a) -0.02 (b) +0.02 (c) 50 (d) cannot be estimated
Stability Theory » Exercise - 123. Asymptotes can intersect : (a) only on the negative real axis (b) only on the positive real axis (c) any where on the real axis (d) none of these
Stability Theory » Exercise - 268. As the polar plot gets closer to the (-1 + j0) point, the stability of the system is : (a) improved (b) reduced (c) not affected (d) none of these
Stability Theory » Exercise - 145. Because of the addition of a zero to G(s)H(s), the stability of the system is : (a) improved (b) reduced (c) not affected (d) none of these
