Text Solution

Verified by Experts

Logic gate. A logic gate is a digital circuit, which works according to some logical relationship between input and ouput voltages.
Nor Gate. When the output of OR gate is connected to the input of NOT gate we get a NOR gate as shown in figure (a) .

Logic symbol of NOR gate is shown in fig. (b).
Truth table. The truth table of NOR gate
