XNOR gate is one of the basic logic gates. It gives HIGH output when both inputs are same. If both inputs are 0 or both are 1 then output is 1. If one input is 0 and other is 1 then output is 0. It is also called an “Equivalence Gate”. This Logic XNOR Gate […]
Logic XOR Gate Circuit with Transistors
This is project is for Logic XOR Gate Circuit with Transistors It uses transistors and resistors. It shows how XOR logic works. Output is high only when inputs are different. Good for students and beginners to learn digital logic. Truth Table for Logic XOR Gate: Input A Input B Output Y (A ⊕ B) 0 […]
Logic NOR Gate Circuit with Transistors
NOR gate is a universal logic gate. It gives output HIGH only when all inputs are LOW. It performs both OR and NOT operation together. In this circuit two NPN transistors are used to make NOR logic. Truth Table for Logic NOR Gate: Input A Input B Output Y 0 0 1 0 1 0 […]
