Chapter 5, Problem 32P

(a)

To determine

Sketch $v_o$ versus $\alpha$ for the ideal op amp when $R_f=4R_1$ and $v_g=2\text{V}$ by using increments of 0.1 and with hypothesis that $0\le \alpha \le 1.0$.

(b)

To determine

Write the expression for the straight line plotted in Figure 1. And also mention how are the slope and intercept of the line related to $v_g$ and the ratio $\frac{R_f}{R_1}$.

(c)

To determine

Find the values of $v_g$ and the ratio $\frac{R_f}{R_1}$ such that $v_o=-6a+4$.
