Question

write preface on topic logic gates for class 12th

Answer 1

Logic gates are the basic components in digital electronics. They are used to create digital circuits and even complex integrated circuits. For example, complex integrated circuits may bring already a complete circuit ready to be used – microprocessors and microcontrollers are the best example – but inside them they were projected using several logic gates. In this tutorial we will teach you everything you need to know about logic gates, with several examples.

Answer 2

logic gates are AND gate, OR gate and NOT gate.

AND gate :

AND gate is both inputs are high, output is high.

OR gate :

OR gate is at least one input is high, output is high.

NOT gate :

NOT gate is input is high, output is low, vice versa.
