Logic gates using transistors and diode | Proteus design suite simulation

My website: Logic gates are semiconductor devices. It is building block of any digital device. It has basically two input terminals and one output terminal. On the input terminals, we provide digital signal and on the output terminal it provides a digital output. To know operations of various types of logic gates we first need to know what digital signal is? Now, let’s get to the main topic which is logic gates. There are three basic logic gates which are AND, OR and NOT. Many logic gates can be formed through these three universal logic gates. Important extracted gates are NAND, NOR, Exclusive-OR (XOR), Exclusive-NOR (XNOR) etc. XOR and XNOR are called universal logic gate because using these gates we can implement any boolean expression and build that ciruit. AND gate It has two or more input terminal and one output terminal. It performs AND operation which means input 1 and input 2 both should be true or high for high output. Let it understand through figures an
