diff-amp shown in Figure has a differential voltage gain of 2500 and a CMRR of 30,000. In part (a), a single-ended input signal of 500 rms is applied. At the same time a 1 V, 60 Hz common-mode interference sig nal appears on both inputs as a result of radiated pick-up from the ac power system. In part (b), differential input signals of 500 uV rms each are applied to the inputs. The common-mode interference is the same as in...
