The XNOR Gate: The logic symbol is the same as the XOR gate with an inversion bubble placed at the output side. The exclusive NOR gate produces an inverted output as that of the XOR gate. Learning Objectives: Introducing XNOR gate implementation using Switches Diodes BJT Working: Case 1: Input A = 0…
The logic symbol is the same as the OR gate with an inversion bubble placed at the output side. Its function is NOT-OR. It has a similar truth table to that of a NAND gate. Its output is high only when both of the inputs are low. The logic symbol is the same as the…
The OR gate performs logical OR function. The output is high when any one input is high. The OR gate is widely used in digital circuits, alarm systems, and even microprocessor logic. In this post, we will explore the OR gate from different perspectives, including: Learning Objectives: Working: Case 1: Case 2: Case 3: Case…
The logic symbol is the same as the AND gate with an inversion bubble placed at the output side. Learning Objectives: Working Of NAND Gate: Case 1: Input A = 0 Input B = 0 Output = 1 Case 2: Input A = 0 Input B = 1 Output = 1 Case…
Outline: What is an algorithm with examples Properties Representation Pseudocode Flowcharts Examples An algorithm is a term commonly used in computer science and mathematics. It is a ‘problem-solving method’. You must be familiar with this term. It is the finite set of instructions, logic and step by step procedure execute in a finite amount of time. You can…
Hexadecimal Division Examples This is my fourth and last article on hexadecimal arithmetic. In this post I will solve some examples on hexadecimal number system division. Before starting this topic you should know how to multiply hexadecimal numbers. Here is my article on hexadecimal numbers multiplication. Key Questions: How to perform division base 16 or…
Binary Subtraction Solved Examples This is my second article on binary arithmetic. In this post, I will provide solved examples of binary numbers subtraction. When dealing with negative numbers you should know about the complement of a number. Before starting this post I would like to recommend you to know about the complement system and…
Understanding the representation of numbers in computer science is crucial. Do you know how a computer handles negative numbers or fractional numbers? You’ve already learned about numbers in mathematics in earlier classes, but there are specific terminologies used when studying number systems in computer science. I would like to explain these as well.In computer science,…
