Master Slave Digital Clock
In industries, master-slave digital clock is a digital clock system widely used for precise and coordinated time-keeping. In this article, we will discuss the construction, working, advantages, and applications of the master slave digital clock. Thus, let us start with the basic introduction of the master-slave digital clock. What is a Master-Slave Digital Clock? A type digital clock system which consists of a master-clock and one or more slave-clocks is referred to as a master slave digital clock. The master clock performs a function of sending a timing signal to the slave clocks, so that the slave clocks can ...
Read MoreLockout Condition in Counter
A digital counter is a sequential logic circuit which counts the number of clock pulses or events that occur over time. Now, let us discuss the lockout condition in counter. What is Lockout Condition in Counter? In digital counters, the condition wherein the counter enters to an unused state and rather than coming out of this unused state to a valid state or initial state, it switches to another invalid or unused state and gets stuck up in the cycle of unused states only, is known as the lockout condition in the counter. Therefore, in the case of lockout condition, ...
Read MoreGeneralized Number Systems
What is a Generalized Number System? A mathematic structure which can extend the properties of the conventional number system like integers, real numbers, rational numbers, complex numbers, etc. to a more general case is known as a generalized number system. The major applications of generalized number systems include many areas of mathematics such as algebra, analysis, number theory, topology, etc. In more simple terms, a generalized number system can be defined as the generalization of the conventional/traditional number systems. Importance of Generalized Number Systems Generalized number systems are considered an important part of modern mathematics and science because they provide ...
Read MoreEdge-triggered Latches
In digital circuits, a latch is a sequential logic circuit which has two stable states. Hence, a latch is also called as a bistable-multivibrator. A latch has capacity to store 1-bit of information. A latch has one or more inputs and two outputs. The outputs of a latch are specified by Q and Q'. Where, Q is the normal output of the latch and Q' is the inverted output. The block diagram of a latch is shown in Figure-1. In this article, we will discuss about the edge triggered latches, their types, applications. So, let us start with the ...
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 ...
Read MoreWhat is the Nature of Electricity?
Electricity is form of energy that is obtained from other form of energy such as chemical energy, nuclear energy, heat energy, solar energy, etc. available in the nature. Electricity is the phenomenon associated with the existence and motion of the electric charge in the matter. This article is meant for explaining the nature of electricity. But before that we will understand the concept of electricity and is existence. The Concept of Electricity Electricity, also referred to as electrical energy, is a form of energy which is usually obtained from other forms of energy present in the nature. Electricity is a ...
Read MoreWhat is Space Charge – Definition, Causes, and Consequences
The collection of electrons (electric charge) at a short distance away from a metal surface forming a cloud of electric charge around the metal surface is known as space charge. These electrons are emitted from the metal surface on the application of electric field. In other words, the space charge is defined as the spatial distribution of electric charge within an insulating medium. In this article, we will discuss the definition and consequences of the space charge. What is Space Charge? As discuss above, the space charge is the accumulation or collection of electric charge in a particular region within ...
Read MoreWhat is Regulated Power Supply? – Circuit Diagram, Operation, and Applications
We have several electrical and electronic circuits that require a DC power supply to operate. But, due to some technical and economical limitations, we cannot use conventional sources of DC power such as batteries and DC generators. In this situation, we use an electronic circuit that can convert AC power into DC power, such a circuit is known as rectifier. However, the DC power output of a rectifier is a fluctuating DC voltage and current which may damage the electronic circuit. Thus, to overcome the problem of variation in voltage, some voltage regulating devices are used so that we can ...
Read MoreWhat is Open Circuit Voltage? – Definition, Calculation, and Example
In electrical and electronic circuits, the difference between potentials of two points is referred to as voltage or potential difference. Sometime we come across a term "open circuit voltage" while analyzing electric circuits. The term open circuit voltage is very common when we use Thevenin’s Theorem to analyze the circuit. Therefore, in this article, we will discuss what the open circuit voltage is, and how to calculate and test it. So let’s begin with a basic introduction of the open circuit voltage. What is Open Circuit Voltage? In an electric circuit, when a gap or open is created, and the ...
Read MoreWhat is Direct Current? – Definition, History, Measurement, and Applications
In electrical and electronics, the term electric current (or current) is used to represent the flow of electric charge (electrons or holes) in a particular direction. Hence, the electric current is simply defined as the directed flow of electrons (in metals), and electrons and holes (in semiconductors). In actual practice, the electric current can only flow through metals and semiconductors, while insulators block the flow of electric current through them. Based on the direction of flow, the electrical current is broadly classified into two types namely direct current (DC) and alternating current (AC). In this article, we will discuss the ...
