Looking at some time domain data and wondering what the frequency is present (Picture 6)? Picture 6: Damped sine wave time history. 8 1 t y(t) ζ = 1 Critically damped y(t) = 1 - exp( - ωnt ) [1 + ωnt] 2 4 6 8 10 1 t y(t) ζ < 0 Underdamped y(t) = 1 - exp( - ζωn t) cos( ωd t) + ζωn ωd sin(ωd t) First peak*, ΜP = 1 + exp. This is counter to our everyday experience. Damping Functions 2 - Cool Math has free online cool math lessons, cool math games and fun math activities. Start studying Hearing Speech Science Exam 1. I know labview (CLAD certified) but not so much on signal processing. By using Microsoft Excel, we can easily create a graph sine, cosine graphs, charts and graphs tangent of the other trigonometric functions. The weight will continue to vibrate, or oscillate, at an amplitude that will slowly decrease due to frictional losses. Thus the mean squared amplitude has the same role as the rms value of a periodic function.
