Electronic Repair Technician Interview Questions and Answers

There are several types of gates in electronics, including AND, OR, NOT, NAND, NOR, XOR, and XNOR gates.

• AND gate: output is high only when all inputs are high

• OR gate: output is high when any input is high

• NOT gate: output is the inverse of the input

• NAND gate: output is low only when all inputs are high

• NOR gate: output is low when any input is high

• XOR gate: output is high when only one input is high

• XNOR gate: output is high when all inputs are either high or low

A logic gate is an electronic component that performs a logical operation on one or more binary inputs to produce a single binary output.

• Logic gates are the building blocks of digital circuits.

• They are used to implement Boolean functions and perform logical operations such as AND, OR, NOT, XOR, etc.

• Examples of logic gates include AND gate, OR gate, NOT gate, NAND gate, NOR gate, XOR gate, XNOR gate, etc.
