Can XOR gate have 3 inputs?

If the inputs are the same the output is low. Hence this truth table: You can find a XOR gate that have more than two inputs, but they are not actually a 3 input XOR. They XOR input A and B and the result of them "R" is then XOR with input C. And the result of R XOR C is then XOR with input 4 and so on.

How many inputs can be in a AND gate?

The truth table for a NAND gate is as one might expect, exactly opposite as that of an AND gate: As with AND gates, NAND gates are made with more than two inputs. In such cases, the same general principle applies: the output will be “low” (0) if and only if all inputs are “high” (1).
  • What is the logic circuit?

    In electronics, a logic gate is an idealized or physical device implementing a Boolean function; that is, it performs a logical operation on one or more binary inputs and produces a single binary output.
  • Why logic gates are used?

    A logic gate implements a Boolean function and thus performs a logical operation on one or several logic inputs in order to produce a single logic output. A logic gate often uses diodes or transistors that act like electronic switches.
  • How does the transistor work?

    A transistor is a miniature electronic component that can do two different jobs. It can work either as an amplifier or a switch: When it works as an amplifier, it takes in a tiny electric current at one end (an input current) and produces a much bigger electric current (an output current) at the other.
