The voltage signals V1 and V2 are read from a transducer. If the output impedance of the transducer is 500O, then find the differential gain (Ad ) and common mode gain Acm of differential amplifier. Assume R1 = 100O and R2 = 200O. Find the value of CMRR and comment on the calculated CMRR. Is this CMRR acceptable? Note: You could represent V1 and V2 by their thevenin equivalent circuits.
