Logic gate:

  • Logic gate is an electronic circuit that is used to perform logic decisions based on the input.
  • It contains one or more number of inputs and one output.
  • The working of logic gate is based on the binary principle that has two states either logic 0 or logic 1.
  • The output of logic gate is produced when it satisfies any of its logic conditions.
  • The logic condition depends upon the type of the gates and the number of inputs.
  • The primary logic gates include AND, OR, and NOT and the combinations of these gates are used to implement any of the other logic gates.

The NAND logic gate is universal, meaning that using gate alone, we can implement any of the other logic gates. Find a way to define NOT, AND, and OR, using only NAND gates and the input variables I and y. (a) NOT(2) = (b) AND(x, y) = (c) OR(x, y) =
The following logic circuit has four inputs A, B, C, and D. Write the Boolean expression for X. Can we simplify it?
