1.2 An accelerometer has critically damped, second-order, low-pass dynamics with the transfer function: Vo KA * (6) = (28+1) %3D where T = 1s KA = 0.001 V/(m/s?) %3D Given a step input of acceleration at t 0, find how long it will take v,(t) to reach the following: (A) 95% of its SS value, (B) 99% of its SS value, and (C) 99.9% of its SS value. A piezoelectric pressure sensor and its signal conditioning amplifier have a transfer function approximated by %3D 1.3 Vo (s) s100 +1 -10s P. The input is a 100 psi pressure step. (A) Sketch and dimension v,(t). (B) Find the peak v.(t). (C) Find the time for v,(t) to drop to 99.5% of its peak value.
