Half Subtractor Circuit and Its Construction In previous tutorials, we have seen how computer use binary numbers 0 and 1 and by using an adder circuit computer will add those digits to provide SUM and Carry Out. We have already covered Half Adder and Full Adder circuits in previous tutorials. Today we will learn about Subtractor circuits. Subtractor circuits use this binary numbers 0, 1 and calculate the subtraction.… |

XNOR Gate XNOR or EX-NOR gate is a digital logic gate, designed for arithmetic and logical operations. Here we are going to use 74LS86 chip for demonstration, this chip has 4 EX-OR gates in it. These four gate are connected internally as shown in below figure. These EX-OR gates are followed by NOT gates. These gates provides… |
