![]() Reason out why the NAND and NOR are called universal gates? In simple words, the output is 1 if the input is the same, otherwise, the output is 0. ![]() Its output is “true” if the inputs are the same, and “false” if the inputs are different. The XNOR (exclusive – NOR) gate is a combination XOR gate followed by an inverter. The fundamental logic gates are AND, OR, and NOT gates. Write the truth table of fundamental gates. NAND, NOR, XOR and XNOR are derived gates. ![]() The logic gates which are derived from the fundamental gates are called derived gates. In other words, the output of the NAND gate is 0 if and only if both the inputs are 1, otherwise the output is 1. The output is “false” if both inputs are “true” otherwise, the output is “true”. It acts in the manner of the logical operation “AND” followed by an inversion. The NAND gate operates an AND gate followed by a NOT gate. It describes the relationship between inputs and outputs of a digital circuit. Which gate is called as the logical inverter?īoolean algebra is a mathematical discipline that is used for designing digital circuits in a digital computer. ![]() Which is a basic electronic circuit which operates on one or more signals? ![]()
