Amplitude ratio M(@) Example: An Accelerometer is to selected to measure a time-dependent motion. In particular, input signal frequencies below 100 Hz are of prime interest. Select a set of acceptable parameter specifications for the instrument, assuming a dynamic error of ±5% and damping ratio =0.7 Solution: ≥ 1047 rad/s 1.5 1 1.05 0.95 0.5 0 0.1 w/ @n 0.5 1 2 Amplitude ratio M(@) 2. 1.5 1.05 0.5 0.95 0 0.1 0.5 1 2 w/ @n
