Verify, using simulations, that the circuit in Fig. 26.9 does indeed amplify the difference between V
_{b l a s p}
and the average on the + inputs of the amplify. Comment on the operation of the circuit, making sure it is clear that the limitations, uses, and operation of the amplifier are understood.
