Short Wave Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna with the purpose of signal transmission to a radio receiver. The transmitter itself generates a radio frequency alternating current, which is applied to the antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio, such as radio (audio) and television broadcasting stations, cell phones, walkie-talkies, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for communication purposes; or radiolocation, such as radar and navigational transmitters. Generators of radio wav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flag Of The Netherlands
The national flag of the Netherlands () is a horizontal tricolour (flag), tricolour of red, white, and blue. The current design originates as a variant of the late 16th century orange-white-blue ''Prince's Flag, Prinsenvlag'' ("Prince's Flag"), evolving in the early 17th century as the red-white-blue ''Statenvlag'' ("States Flag"), the naval flag of the States General of the Netherlands#Dutch Republic, States-General of the Dutch Republic, making the Dutch flag the oldest Tricolour (flag), tricolour flag in continuous use. As a flag that symbolises the transformation from monarchy to republic, it has inspired both the derivative Flag of Russia, Russian flag, and after the French Revolution in 1789, the vertically striped Flag of France, French tricolour; both flags in turn influenced many other tricolours. During the 1920s and the economic crisis of the 1930s, the old Prince's Flag with the colour orange gained some popularity among Dutch Reformed Church, Protestants, Orangis ...

Broadcast Transmitters
Broadcasting is the distribution of audio audiovisual content to dispersed audiences via a electronic mass communications medium, typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and receivers. Before this, most implementations of electronic communication (early radio, telephone, and telegraph) were one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as early as 1898. Over-the-air broadcasting is usually associated with radio and television, though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
