Amplitude Modulation
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the amplitude (signal strength) of the wave is varied in proportion to that of the message signal, such as an audio signal. This technique contrasts with angle modulation, in which either the frequency of the carrier wave is varied, as in frequency modulation, or its phase, as in phase modulation. AM was the earliest modulation method used for transmitting audio in radio broadcasting. It was developed during the first quarter of the 20th century beginning with Roberto Landell de Moura and Reginald Fessenden's radiotelephone experiments in 1900. This original form of AM is sometimes called double-sideband amplitude modulation (DSBAM), because the standard method produces sidebands on either side of the carrier frequency. Single-sideband modulation uses bandpass filters to eliminate one of the sidebands and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warrnambool
Warrnambool ( Maar: ''Peetoop'' or ''Wheringkernitch'' or ''Warrnambool'') is a city on the south-western coast of Victoria, Australia. At the 2021 census, Warrnambool had a population of 35,743. Situated on the Princes Highway, Warrnambool (Allansford) marks the western end of the Great Ocean Road and the southern end of the Hopkins Highway. History Origin of name The name "Warrnambool" originated from Mount Warrnambool, a scoria cone volcano 25 kilometres northeast of the town. Warrnambool (or Warrnoobul) was the title of both the volcano and the clan of Aboriginal Australian people who lived there. In the local language, the prefix Warnn- designated home or hut, while the meaning of the suffix -ambool is now unknown. William Fowler Pickering, the colonial government surveyor who in 1845 was tasked with the initial planning of the township, chose to name the town Warrnambool. The traditional Indigenous owners of the land today are the Dhauwurd Wurrung people, also known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frequency Modulation
Frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and Run-length limited#FM: .280.2C1.29 RLL, computing. In Analog signal, analog frequency modulation, such as radio broadcasting, of an audio signal representing voice or music, the instantaneous frequency deviation, i.e. the difference between the frequency of the carrier and its center frequency, has a functional relation to the modulating signal amplitude. Digital data can be encoded and transmitted with a type of frequency modulation known as frequency-shift keying (FSK), in which the instantaneous frequency of the carrier is shifted among a set of frequencies. The frequencies may represent digits, such as '0' and '1'. FSK is widely used in computer modems, such as fax modems, telephone caller ID systems, garage door openers, and other low-frequency transmissions. R ...

Hamilton, Victoria
Hamilton is a large town in south-western Victoria, Australia, at the intersection of the Glenelg Highway and the Henty Highway. The Hamilton Highway connects it to Geelong. Hamilton is in the federal Division of Wannon, and is in the Southern Grampians local government area. Hamilton claims to be the ''"Wool Capital of the World"'', based on its strong historical links to sheep grazing which continue today. The town uses the tagline "Greater Hamilton: one place, many possibilities". History Early history Hamilton was built near the border of three traditional indigenous tribal territories: the Gunditjmara land that stretches south to the coast, the Tjapwurong land to the north east and the Bunganditj territory to the west. People who lived in these areas tended to be settled rather than nomadic. The region is fertile and well-watered, leading to an abundance of wildlife, and no need to travel far for food. Physical remains such as the weirs and fish traps found in Lake Cond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portland, Victoria
Portland is a city in Victoria, Australia, and is the oldest European settlement in the state. It is also the main urban centre in the Shire of Glenelg and is located on Portland Bay. As of the 2021 census the population was 10,016, increasing from a population of 9,712 taken at the 2016 census. History Early history The Gunditjmara, an Aboriginal Australian people, are the traditional owners of much of south-west Victoria, including what is now Portland, having lived there for thousands of years. They are today renowned for their early aquaculture development at nearby Lake Condah. Physical remains such as the weirs and fish traps are to be found in the Budj Bim heritage areas. The Gunditjmara were a settled people, living in small circular weather-proof stone huts about high, grouped as villages, often around eel traps and aquaculture ponds. On just one hectare of Allambie Farm, archaeologists have discovered the remains of 160 house sites. 19th century European settlement ...

Victoria (Australia)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolit ...

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...

Australian Broadcasting Corporation
The Australian Broadcasting Corporation (ABC) is the national broadcaster of Australia. It is principally funded by direct grants from the Australian Government and is administered by a government-appointed board. The ABC is a publicly-owned body that is politically independent and fully accountable, with its charter enshrined in legislation, the ''Australian Broadcasting Corporation Act 1983''. ABC Commercial, a profit-making division of the corporation, also helps to generate funding for content provision. The ABC was established as the Australian Broadcasting Commission on 1 July 1932 by an act of federal parliament. It effectively replaced the Australian Broadcasting Company, a private company established in 1924 to provide programming for A-class radio stations. The ABC was given statutory powers that reinforced its independence from the government and enhanced its news-gathering role. Modelled after the British Broadcasting Corporation (BBC), which is funded by a tel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
