Chapter 2, Problem 2.61P

Consider the circuit in Figure P2.61. The output of a diode OR logic gate is connected to the input of a second diode OR logic gate. Assume $V_{\gamma }=0.6\text{V}$ for each diode. Determine the outputs $V_{O1}$ and $V_{O2}$ for (a) $V_1=V_2=0$ ; (b) $V_1=5\text{V}$ , $V_2=0$ ; and (c) $V_1=V_2=5\text{V}$ . What can be said about the relative values of $V_{O1}$ and $V_{O2}$ in their “high” state?
