The RCA connector [3] is a type of electrical connector commonly used to carry audio and video signals. The name RCA derives from the company Radio Corporation of America, which introduced the design in the 1930s. [4] The connector’s male plug and female jack are called RCA plug and RCA jack . It is also called RCA phono connector [5] or ...
It does not appear, however, that any of this information was used by Blair. Radio-based target detection. The SCL's first definitive efforts in radio-based target detection started in 1934 when the Chief of the Army Signal Corps, after seeing a microwave demonstration by RCA, suggested that radio-echo techniques be investigated.
RCA jacks (phono connectors) jack plugs; Example. The widely used RS-232 system is an example of single-ended signaling, which uses ±12 V to represent a signal, and anything less than ±3 V to represent the lack of a signal. The high voltage levels give the signals some immunity from noise, since few naturally occurring signals can create a ...
Composite video is an baseband analog video format that typically carries a 525 or 625 line interlaced signal on a single channel, unlike the higher-quality S-Video (two channels) and the even higher-quality component video (three or more channels). A yellow RCA connector is typically used for composite video, with the audio being carried on ...
Radio navigation. Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object on the Earth, either the vessel or an obstruction. [1] [2] Like radiolocation, it is a type of radiodetermination . The basic principles are measurements from/to electric beacons, especially.
Doppler radio direction finding, also known as Doppler DF, is a radio direction finding method that generates accurate bearing information with a minimum of electronics. It is best suited to VHF and UHF frequencies and takes only a short time to indicate a direction. This makes it suitable for measuring the location of the vast majority of ...
A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.
A Bluetooth -based key finder. Key finders, also known as keyfinders, key locators, or electronic finders, are small electronic devices fitted to objects to locate them when misplaced or stolen, such as keys, luggage, purses, wallets, pets, laptop computers, toddlers, cellphones, equipment, or tools, and to transmit alerts, e.g., that one's ...
