Repeat Problem 1 for a 2 mV, 1 kHz input signal.

Problem 1

With a 1 mV, 50 Hz signal applied to the ECG amplifier board in Figure 1, what voltage would you expect to see at each of the probed points? All voltages are measured with respect to ground (not shown). Assume that all offset voltages are nulled out and the position control is adjusted for zero deflection. The gain adjustment potentiometer is set at midrange. Refer to the schematic in Figure 1.
