Antenna used for transmission of radio signals. In telecommunications, transmission (sometimes abbreviated as "TX") is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic. [1] [2]
A signaling protocol is a type of communications protocol for encapsulating the signaling between communication endpoints and switching systems to establish or terminate a connection and to identify the state of connection. The following is a list of signaling protocols: ALOHA; Digital Subscriber System No. 1 (EDSS1) Dual-tone multi-frequency ...
An area at the very end of a drag strip to slow down and stop vehicles that have gone off the track, as a safety measure. It is filled with, as the name implies, sand. satellite team A second racing team either operated by or in partnership with a larger team, but maintaining a separate identity.
In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. Flow control should be distinguished from congestion control , which is used for controlling the flow of data when congestion has actually occurred. [ 1 ]
[6] [7] Nonverbal communication can portray a message both vocally and with the correct body signals or gestures. Body signals comprise physical features, conscious and unconscious gestures and signals, and the mediation of personal space. [6] The wrong message can also be established if the body language conveyed does not match a verbal message.
An optical communication system is any form of communications system that uses light as the transmission medium. Equipment consists of a transmitter, which encodes a message into an optical signal, a communication channel, which carries the signal to its destination, and a receiver, which reproduces the message from the received optical signal.
A pulse on one signal indicates when another bit of information is ready on the other signal. The asynchronous signalling methods use only one signal. The receiver uses transitions on that signal to figure out the transmitter bit rate (" autobaud ") and timing, and set a local clock to the proper timing, typically using a phase-locked loop (PLL ...
The BCI was introduced by Vidal in 1973 [113] as challenge of using EEG signals to control objects outside human body. After the BCI challenge, in 1988, alpha rhythm was used in a brain rhythm based BCI for control of a physical object, a robot. [114] [115] Alpha rhythm based BCI was the first BCI for control of a robot.
