Consider the AND logic circuit in which V2 = 3 V and V1 lie between 0 to 5 V. The output voltage is V0. The cut-in voltage of diode D1 and D2 is 0.6 V. The output voltage V0 versus V1 corresponding to the below network is

Consider the AND logic circuit in which V2 = 3 V and V1 lie between 0 to 5 V. The output voltage is V0. The cut-in voltage of diode D1 and D2 is 0.6 V. The output voltage V0 versus V1 corresponding to the below network is Correct Answer <img alt="F1 S.B 1.9.20 Pallavi D10" src="//storage.googleapis.com/tb-img/production/20/09/F1_S.B_1.9.20_Pallavi_D10.png" style="width: 151px; height: 165px;">

Concept:

Whenever diodes are tied together, the diode which experiences the more potential difference will ON first.

When all diodes are opposite to the previous case.

V0 = 2.6 V

For V1 = 3 V

Both will be ON

V0 = 3.6 V

For V1 = 4 V diode D1 will be OFF.

V0 = 3.6 V

For V1 = 5 V diode D1 will be OFF.

V0 = 3.6 V

So the output is constant at 3.6 V for V1 ≥ 3 V

Option B is correct.

You are the administrator of a Windows 2000 Server computer. The server contains one network adapter and is a file and print server for critical company resources. You install a second network adpater in the server and connect it to the same network subnet as the first adapter. You want to ensure that the first adapter is used for all network traffic and the second adapter is used only if the first adapter fails or is disconnected from the network. You also want to ensure that the server always has network connectivity even if one network adapter fails. What should you do?
