Assume the two op amps are ideal. (a) Write an equation for the output voltage, vo, in terms of the input voltage, vi , and the three resistors R1, R2, and R3. [5 points] (b) Select resistors R1, R2, and R3 such that |vo| = 100|vi |. [5 points] (c) Suppose both op amps have ±25 V supply voltages and the resistors satisfy part (b). What is the maximum input voltage for which this amplifier remains in the linear region (i. e., the op amps do not saturate)? [5 points] (d) What sort of amplifier is this (inverting, noninverting, neither)?
