A second order pressure transducer has an undamped natural frequency of 300 rad/s, damping ratio of 0.1 and a static sensitivity of 10-6 V/N/m2 . It is connected to a second order recording device which has an undamped natural frequency of 400 rad/s damping ratio of 0.5 and static sensitivity of 5 mm/mV. If the input is a sinusoidal pressure signal of amplitude 1000 N/m2 and frequency 30 Hz., find the value of the output amplitude as recorded and the phase difference between the input and output signals.
