Digital logic, the most prominent term which we are aware of today required the cooperation and support of hundreds and thousands of people over many years and decades. Before the invention of electronic devices, mathematicians were inadvertently developing binary logic and laying the basis for current-day computing equipment. These approaches were later employed for the same kind of communication systems such as Morse code and binary. In order to automate the mechanical devices, Charles Babbage … [Read more...]
What is NAND Gate : Working & Its Applications
We all know that logic gate is the idealized computational approach for the implementation of a Boolean function which is either performed on a single or more number of inputs thus generating single output. As per this context, the term can be referred to as an ideal logic gate or non-ideal physical device. These logic gates are basically designed using transistors, relay logics, diodes, and many other mechanical elements. The very fundamental type of logic gates is AND, OR, and NOT gates. Along … [Read more...]
What is OR Gate : Circuit, Truth Table & Applications
We all know that logic gates are the devices that stand as functional blocks for many of the digital circuits. Nearly 90%of the electronic devices are designed with logic gates to perform logical operations in those devices. These logic gates are dependent on Boolean algebra where those will generate output depending on the combination of digital signals from the input bits. Based on the kind of logic and the inputs combinations, the result will vary. The one type of logic gate which we are … [Read more...]
What is Quine-McCluskey Method : Minimization Technique & Examples
Quine McCluskey minimization method, is a technique for reducing for minimizing the expression in their SOP (sum of product) or POS (product of sum) form. Also called a tabular method, this method has advantages over the K Map method, in case the number of input variables is large. For an input variable greater than six, the K Map method becomes more complex. For such problems, McCluskey or Tabular method has a simplified approach. Even it has a simplified approach as compared to other … [Read more...]
What is Binary Arithmetic : Truth Tables & Solved Examples
Computers understand the language of binary. And for all arithmetic operations, algorithms are designed to do arithmetic operations in a binary framework. For all conventional binary arithmetic operations, such as addition, subtraction, multiplication, and division, binary numbers are organized in the form of truth tables. These truth tables form the fundamental basis for all the binary operations. Logic circuits are designed and implemented based on the truth tables. These logic gate circuits … [Read more...]
What is AND Gate : Truth Table, Working & Its Applications
In the domain of digital electronics logic gates are the devices that perform Boolean operations having two inputs and one output. Depending on the logical gate, the logical functionality changes and the output also gets varied. In the year 1886, in a letter, Charles Pierce stated that how logical functionalities could be performed by switching circuits. Finally, vacuum tubes got replaced by logical operations. And the one logical gate which we are going to discuss today is AND gate. The first … [Read more...]
What is Carry Lookahead Adder : Block Diagram & Its Working
We all know that in the current day technology everything becomes digitized and digital systems are designed based on fundamental configurations like AND, OR, and NOT gate. These configurations are employed in multiple network designs. Apart from performing logical functionalities, systems should also store up binary numbers and for storage purposes, Flip Flop’s are invented. So, for some functionalities, the combination of Flip Flop’s and logic gates are used, and IC’s (Integrated Circuits) are … [Read more...]
What is DeMorgan’s Theorem : Statement & Its Applications
The name for DeMorgan’s laws was named after a British logician and mathematician Augustus De Morgan. The influence behind the invention of these laws was the algebraization of logic carried out by George Boole and later strengthened by DeMorgan's claim to the find. Even though there were many observations made on these principles by Jean Buridan, William of Ockham, and many others, the credit was given for DeMorgan where he specified the laws in the form of contemporary formal logic and in … [Read more...]
Wien Bridge Oscillator : Circuit Diagram & Its Operation
The electronic circuits used to generate periodic, oscillating signals such as sine waves or square wave,s or triangular wave are known as Oscillators. Oscillators take a DC signal and convert them into the required AC signal. These are used in numerous electronic devices where a clock signal is required. Some of the applications of oscillators are clock generators in calculators, computers, digital clocks, video games, etc... The signals generated by oscillators are also used in radio … [Read more...]
What is an LDO Regulator : Working & Its Parameters
When integrating a voltage supply to any other equipment, we may encounter certain unwanted voltage variations. These variations at the voltage supply level can cause severe damage to the devices. So, there is a need to maintain a constant voltage at the supply level. This is where 'Voltage Regulator' comes into the picture. Voltage regulators are the devices that maintain a stable output voltage irrespective of the changes at the input voltage and load. Based on their design there are various … [Read more...]
