I explained De Morgan’s Law earlier. In this tutorial, I will solve some problems on this topic. Bubble pushing is another important technique, that should be addressed in this topic. Learning Objectives: I will show step-by-step procedures for bubble logic or bubble pushing. There is a detailed explanation for two examples while the rest are solved directly.…
The first simplest and most fundamental logic circuits used in digital electronics is a buffer. A buffer is a single-input, single-output logic gate. The output is exactly same as the input. In essence, a buffer is a device that amplifies or strengthens the signal it receives. While it does not change the logic state of the…
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 XOR gate with an inversion bubble placed at the output side. Learn more about basic logic gates. Learning Objectives: Working of XOR gate: Case 1: Input A = 0 Input B = 0 Output = 0 Case 2: Input A = 0 Input B =…
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: OR Gate Simulator Select a gate, toggle the…
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…
The AND logic gate performs logical AND function. The output is HIGH (true) only when all the inputs are HIGH (true). Or in other words, if all inputs are non-zero, the output of this gate goes HIGH (non-zero). Or if any of the input is low the output remains low. There is a kit available…
Analysis Of Algorithms – Time Complexity & Space Complexity Analysis Of Algorithms Outline: Analysis of an algorithm Time complexity Types of time functions/Order of algorithm Space complexity In this lesson, you will learn about the theoretical aspect of the algorithms. In the previous lesson, you have learnt about algorithms. Whenever you design an algorithm, you should…
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…
