Problem 7 (15 points): The two input signals of an instrumentation amplifier (which has an 80 dB CMRR) are, 1 = 2 cos 8 + + 0.1 cos 2 2491 + theta 2 = 2 cos 8 + − 0.1 cos 2 2491 + theta The difference mode component of the signal is the desired signal while the common mode signal is considered noise. a) [5 points] Find the SNR in dB at the input of the IA. b) [5 points] Find the SNR in dB at the output of the IA. c) [5 points] If the output of the IA is connected to a filter with the transfer function, H = 3 + 3 Find the SNR in dB at the output of the filter.
