Chapter 2, Problem 2.9EP

Consider the circuit shown in Figure 2.38, in which the diode cut−in voltages are $V_{\gamma }=0.6\text{V}$ . Plot ${\upsilon }_O$ versus ${\upsilon }_I$ for $0\le {\upsilon }_I\le 10\text{V}$ . (Ans. For $0\le {\upsilon }_I\le 3.5\text{V}$ , ${\upsilon }_O=4.4\text{V}$ ; for ${\upsilon }_I>3.5\text{V}$ , $D_2$ turns off; and for ${\upsilon }_I\ge 9.4\text{V}$ , ${\upsilon }_O=10\text{V}$ )
