The figures below show a circuit to condition the signal of a givensensor. Lets assume
that the sensor signal is
vsensor = 1.8 + 0.3 sin (120πt) [v]

a) What should the values {Vref ;RS;RF ; VS} be, such that weeliminate the sensor
offset (1.8[V]) and amplifies the signal in the range ±5[V]to be fed into an A/D
converter for data logging.
b) If the signal has noise above 1[kHz], design a passive low-passfilter (or augment
the circuit above - active low-pass filter) to reduce the noise inthe signal.
