Question

What is NAND gate. Draw its symbol. Write truth table and draw its output single in wave form.

Accepted Answer

A NAND gate can have two or three inputs. Using the combination of these inputs one single output is obtained using the NAND gate.
The simple NAND gate uses diodes and transistors in its construction. The resistor transistor switches are used in the construction of the NAND gate. The switches are connected in the input of the NAND gate. The input is given to the base of the transistor. Two transistors are used in the circuit diagram of the NAND gate. The

The logic NAND gate is the combination of the NOT and gate. The input of the AND gate is inverted using the NOT gate in the NAND gate. So, the output is also modified from the AND gate.
