Amplitude modulation is a type of modulation where the carrier signal’s amplitude is varied in accordance with the information bearing signal. The amplitude modulated signal’s envelope or boundary embeds the information bearing signal. The total power of the transmitted signal varies with the modulating signal, whereas the carrier power remains constant. A nonlinear device combines the carrier and the modulating signal to generate an amplitude modulated signal. The nonlinear device’s output consists of discrete upper and lower sidebands. A nonlinear device’s output does not vary in direct proportion with the Read More

An HTML editor is a type of software that allows users to create and manage HTML elements on a web page. There are three different types of HTML editors: text-based, object-based, and WYSIWYG (What You See Is What You Get). Text-based HTML editors consist of text only and require the user to type in HTML tags and content. Text-based HTML editors can often manage HTML, CSS, and a number of other programming languages and may include a number of features for automatically inserting HTML tags. Object-based HTML editors allow users Read More

Laser hair removal, as its name suggests, is using a laser to remove any hair that is unwanted. The majority of the process is done with a thin light beam of laser passing through the area of the skin that is being treated. Within the skin, specifically the dark pigment, also known as the melanin and often found in hairs, is targeted. This process literally hits the hair follicle (the root of where the hair grows). The contact results in the hair follicle being destroyed. Usually, this process results merely Read More

A microphone is an electromechanical device that uses vibration to create an electrical signal proportional to the vibration, which is usually an air pressure wave. There are many different types of microphone, ranging from the old condensers to the modern piezoelectrics. Microphone History Alexander Graham Bell invented the first microphone in 1876 as part of the telephone. Thomas Edison invented the first carbon microphone in 1886, a significant improvement on Bell’s impractical liquid microphone, and the forerunner of the modern microphone. Microphone Types Condenser microphones are a capacitor that has Read More

Quasars are a phenomena that, to this day, continue to baffle and confuse astronomers. There are different theories. One is that a quasar is formed from a super, massive black hole. Another theory is that a quasar is actually a baby galaxy and is at the earliest stages of development. However, since no one really knows what galaxy development is, there is no way to tell if this theory is sound. Other theorists propose that a quasar is the opposite of a black hole and it is allowing new matter Read More

A computer monitor, technically termed as a visual display unit, can be plainly described as an electronic device that transmits information from the computer onto a screen, thereby acting as an interface and connecting the viewer with the computer. At present, computer monitors are available in a variety of shapes, designs, and colors. However, based on the technology used to make computer monitors, they can be broadly categorized into two types. These include CRT (cathode ray tube) and LCD (Liquid Crystal Technology). CRT (Cathode Ray Tube) Monitors These monitors employ Read More

One of the most frustrating things when dealing with a computer is when something goes so wrong with it that there is nothing else that can be done to preserve the computer other than to do a complete factory restore. What this means is that the computer is sent back to a time when it was first shipped out of the factory. While the hardware has still been worn down, there is nothing on it other than the basic programs that came with the computer installation. It should be noted Read More

Database integration means that multiple different applications have their data stored in a specific database – the integration database – so that data is available across all of these different applications. In other words, the data is available between two different parties and therefore, can be easily accessed and implemented into a different application without having to transfer to a different database. For the database integration to work successfully, it needs to have a plan that allows for all of the client applications to be taken into account. Whether the Read More

An ADSL router is also known as a DSL modem. The router connects the computer to the DSL phone line so the ADSL service can be used. Some countries also use the term NTBBA (Network Termination BroadBand Access). There are some ADSL routers that are also capable of sharing a single Internet connection with a group of computers on a network. This system is also known as the residential gateway. The ATU-R Every ADSL router has a functional block called ADSL Terminal Unit-Remote (ATU-R (transceiver). The ATU-R is responsible for Read More
