Difference Between Coarse and Fine Adjustment
Any gadget may be changed to meet the user's choice. In most devices, each controlled element has only one adjustment knob. However, in certain circumstances, there are two adjustment knobs labeled coarse and fine adjustments. The key distinction between the two is the size of the increase in each stage. In coarse adjustment, a tiny movement results in a significant leap, but the converse is true in fine adjustment. Another distinction between coarse and fine adjustment is the range. The coarse adjustment spans the whole range from zero to one hundred percent. On the other hand, the fine adjustment only ...
Read MoreDifference Between SRGB and Adobe RGB
When discussing colour management, it is impossible to avoid comparing sRGB with Adobe RGB. Based on the use case, these two colour spaces have diverse applications in photography, computer monitors, digital art, or digital displays Two colour spaces, or colour space profiles, that are often used in digital photography and visual media are the subject of the argument between sRGB and Adobe RGB. Consider that you are playing about with the settings on your digital camera. Most likely, there will be a colour space selection option that lets you choose between Adobe RGB and sRGB.Both of them have advantages and ...
Read MoreDifference between Impact and Non-Impact Printers
A printer is an output device that produces information or computer outputs on a paper. Depending upon the technology used, printers are classified into two categories namely, Impact Printers and Non-Impact Printers. An impact printer is one that operates by striking a printing head (made up of metal or plastic) against an ink ribbon, whereas a non-impact printer is one that prints characters and graphics without direct physical contact between the printing head and the paper. Read this tutorial to find out more about Impact and Non-impact Printers and how they are different from each other. What is an Impact ...
Read MoreDifference between Electric Field and Magnetic Field
There is a property of space which is caused by the motion of the electric charge, is known as electromagnetic field. There are two component of an electromagnetic field viz. −Electric fieldMagnetic fieldA stationary electric charge produces only an electric field in the surrounding space. If the electric charge is moving, then it also produces a magnetic field. The electric field and magnetic field occupy different planes relative to the cause of the electromagnetic field, i.e., moving charge.Therefore, one of the major difference between electric field and the magnetic field is that the electric field produces around a static electric ...
Read MoreThe Realization of Logic Functions Using NAND Gates
A logic function is a basically a Boolean expression that returns a Boolean value, which is a value that is either TRUE or FALSE. The NAND gate is a universal logic gate, thus it can be used to implement any type of logic function. Read this tutorial to learn how you can realize different logic functions using NAND gates. Let's start with a basic introduction of the NAND gates What is a NAND Gate? A NAND Gate is a type of universal logic gate that one can use to realize any kind logical expression or any other type of logic ...
Read MorePositional Number System
A number is a method used for representing an arithmetic value, measure, or count, of a physical quantity. A number system is defined as a method of naming and representing numbers. The concept of number system helps in defining the rules associated with the numbers and different operations on numbers. A number system is determined with the help of its radix or base. The radix or base of a number system is nothing but the total number of symbols used in the number system for representing the different numbers. For example, in the decimal number system, there are 10 ...
Read MoreBuild an Inverter with a Transistor
In this tutorial, we will discuss the realization of an inverter (NOT gate) with a transistor. But before that let's have a look into the basics of inverter or NOT gate. What is an Inverter (NOT Gate)? An inverter is a single input and single output logic gate that toggles or inverts the logic level (or state) of a single to the opposite state or logic level. The inverter is also known as NOT gate. When a low signal (logic 0) is applied to an inverter, it transforms it to a high signal (logic 1). If a high signal (logic ...
Read MorePositive and Negative Logic in Digital Electronics
In digital electronics, a logic or logic function is one that follows the rules that governs a logical statement. Logics are implemented by using switching networks, where a switching network is one that is designed by interconnecting a finite number of switches. Example − Let "𝒚" is a logic function, then it may be expressed as, $$\mathrm{Y = f\left ( x_{i} \right ) }$$ Where, xi represents the inputs to the logic network or switching network, and y is the output of the network. There is another term associated with the logic function that is the truth table. The truth ...
Read MoreDifference between Decoder and Demultiplexer
Both decoder and demultiplexer are types combinational logic circuits used for implementing different types of digital systems. However, the function of a decoder is completely different from that of a demultiplexer. A decoder is a combination logic circuit that decrypts an input data stream from one format to another, whereas a demultiplexer is a combination circuit that routes the data from one input line to any of the multiple output lines. Read this article to find out more about decoders and demultiplexers and how they are different from each other. Let's start with a basic overview of these two combinational ...
Read MoreWhat is Voltage Regulator 7805 – Internal Block Diagram and Applications
In this article, we will discuss the definition, internal block diagram, circuit configuration, and applications of voltage regulator 7805 IC. Let’s begin with the basic introduction of voltage regulator. A voltage regulator is an essential element of power supplies used in several electrical and electronic devices such as computers, amplifier, automobile alternator, mobile chargers, etc. A voltage regulator is basically an electronic circuit that generates a regulated voltage of fixed value from an unregulated fluctuating voltage. A voltage regulator is required in a circuit because all voltage sources cannot provide a steady voltage due to change in the load current ...
