Suppose we wish to measure a small signal that has a peak-to-peak amplitude of 0.01 V that is riding on top of a 10 VDC offset.

Suppose we wish to measure a small signal that has a peak-to-peak amplitude of 0.01 V that is riding on top of a 10 VDC offset. We can make better use of our A/D range on our digital acquisition system by subtracting 10 V from the signal then amplifying it by a factor of perhaps 50. Design a circuit containing two op-amps that can be used to perform these two operations.
