( ) (1) n xnwhere f is known as the logarithmic decrement. The damping ratio can be obtained by using thefollowing equation3: f / 2r |= (2) 1 - (f / 2r) 2 The equation of motion of a structural system in modal coordinates can be written asfollows: q n + 2| n yn q% n + y2n q n = 0 %% (3)where yn and | n are natural frequency and damping ratio of the nth mode, respectively; qn,q% n and %q%n represent modal displacement, velocity and acceleration, respectively

from the higher to the lower points(Figure 1) in the least time.1 Figure 1. A curve along which a particle is falling under the action of gravity The time required to travel from point P1 to point P2 is given by1, 2 Page 13.1093.3Where v is the particle’s velocity and ds is the arc length through which it is falling. Applyingthe law of conservation of energy we can write for the particleOrSubstituting this for v in the integrand of the first equation and following the steps given inReferences 1 and 2, we can show that 2 x = ½ k (q – sinq), 2 y = ½ k (q – cosq

That is, low pass filters with fairly wide transition bands will not requirenearly as many bits for good performance as high Q-factor band-pass filters will.Following simulation, students implement the IIR filters for a couple of choices of bits (good andrqqt+"qp"Vgzcu"KpuvtwogpvuÓ"VOU542E8933"FUMu to verify the simulation results Page 13.872.5experimentally.
