Potentiometers are simply termed as POTs and these are even called as variable resistors. The main purpose of a potentiometer is to vary the value of resistance in the circuit. Even these can be employed to vary volume, and dim and brightness of a light. There exist various types of potentiometers such as carbon POTs, wired POTs and plastic POTs. The one type which we are going to discuss today is “Digital Potentiometer”. So, let us discuss more on digital potentiometer definition, how it is … [Read more...]

## What is Preprocessor : Definition, Syntax & Its Commands

With the requirement to include file inclusion procedures present in PL/I and BPCL, the preprocessors were introduced in C at the time of 1973 with the request of Alan Snyder. The initial version of the preprocessor provided only file inclusion procedures and string replacement through #include and #define. Whereas the later versions of (John Reiser and Mike Lesk) offered macros together with arguments and conditional compilations. That’s how the development of the preprocessor took place and … [Read more...]

## What is CAN Protocol : Architecture, Working and Types

Formerly, automobile manufacturers used to connect various electronic devices in automobiles using a number of wires through point-to-point connections. This resulted in huge wire connections which were very expensive and bulky. Later, this complicated wiring system got replaced by dedicated wiring that enhanced communication speed between devices and provided high integrity, and was named as controller area network. The CAN was first developed by Bosch in the year 1985 for in-vehicle … [Read more...]

## What is a Digital Voltmeter : Working & Its Advantages

In the domain of electrical and electronics technology, the voltmeter is the crucial device that is extensively applied across various applications for measuring voltage valves. These voltmeters are available mainly in two types analog and digital. Analog voltmeters consist of a pointer that moves on the dial as per the measurement and displays the corresponding reading. With the advancements in technology and rapid development of digital systems, analogue voltmeters are being replaced by … [Read more...]

## What is NOR Gate : Working & Its Applications

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 NOT Gate : Working & Its Applications

In any of the digital circuits, the primary device that holds more prominence is the logic gate. The name logic gates come from the capability of those devices to provide outputs depending on multiple combinations of inputs. These logic gates are mainly categorized as basic logic gates, special purpose, and universal gates. The one basic gate which we are going to discuss today is NOT gate. The inventor of NOT gate was George Boole and he also invented the concept of boolean logic. Today, this … [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...]
