Qno2 Explain with help of symbolic duagram and truth table (2 input 3 the function of an inverter,Or gate,And gate,Nor gate,NAND gate and XOR gate.
Logic gates are useful in the construction of digital systems.
OR gate:
It gives a high output 1 if one or more of its inputs are high. In this + is used to show the OR operation.

Truth table:
AND gate:
AND Gate gives a high output 1 only if all its inputs are high. A dot (.) is used to show the AND operation.

Truth table:
NOR gate:
NOR Gate means NOT-OR gate i.e an OR gate followed by a NOT gate. The outputs of all NOR gates are low if any of the inputs are high.
Symbolic diagram:
Truth table:
NAND Gate:
NAND Gate means NOT-AND gate i.e an AND gate followed by a NOT gate. The outputs of all NAND gates are high if any of the inputs are low.

Truth table:
XOR Gate:(Exclusive OR)
XOR Gate gives high output if either, but not both, of its two inputs are high.
Symbolic diagram:
Truth table:
Inverter or NOT Gate:Inverter produces an inverted version of the input at its output.For example if the input is A, the inverted output is known as NOT A. This is also shown as A with a bar over the top.
