A seismic instrument (a mass that is attached to a spring and a damper) is used to measure a periodid input signal y(t) 0.8 sin(30n t); y is the displacement [cm], and t is time [sec]. This instrument has a damping ratio 0.7. Choose a combination of mass, spring constant, and damping coefficient to provide less than a 6% dynamic error in the output.
