The op amp in the circuit of Fig. P5.32 is ideal. a) Plot vo versus α when Rf = 4 R1 and vg = 2V.
Use increments of 0.1 and note by hypothesis that 0 ≤ α ≤ 1.0.
b) Write an equation for the straight line you plotted in (a). How are the slope and intercept of the line related to vg and the ratio Rf/R1 ?
c) Using the results from (b), choose values for and the ratio Rf/R1 such that vo = -6α +4.
