A6
It is required to measure a flow Q with an accuracy of + 0.01 gpm by using flow sensor that has a
transfer function of Q volts. The original measured signal has a frequency of 0.2 Hz, and the
sensor output impedance is 10 kn.
a- Design and implement a passive filter to attenuate 20 Hz noise to 1 % while having very little
effect on the original signal.
b- Design and implement a conditioning circuit to provide output voltage varies from -5 to 5 V
as the sensor input flow varies from 0 to 4 gpm.
c- Connect the two circuits together considering minimum load effect.
