Reducing the delay of a wire by cutting it in half and inserting a repeater is known as repeater insertion. The cost of this procedure is the additional new delay through the repeater itself, plus power cost because the repeater is an active circuit that must be powered, whereas the plain unrepeated wire was originally an unpowered passive ...
IR blaster with standard 3.5 mm plug IR blaster attached to a cable TV tuner. An infrared blaster (IR blaster) is a device that relays commands from a remote control to one or more devices that require infra-red remote control.
WIRES II - Yaesu did terminate WIRES-II service on Saturday, September 30, 2017 at 06:00 UTC. They suggested in the future, to use the WIRES-X Internet linking system. [2] [3] WIRES-X - Supports the C4FM digital and the voice technology. It enables high sound quality by repeating C4FM digital data as it is via the Internet.
Consumer IR, consumer infrared, or CIR is a class of devices employing the infrared portion of the electromagnetic spectrum for wireless communications. [ citation needed ] CIR ports are commonly found in consumer electronics devices such as television remote controls , PDAs , laptops , computers , and video game controllers.
DirecTV supplies BBCs with all 5-LNB K u /K a-band dish systems. The satellite signal from T10 is downconverted at the dish to the frequency range of 250-750 MHz, called "K a-lo". At the receiver when necessary, the BBC in response to a control signal from the receiver blocks any original "K a-hi" signals between 1650-2150 MHz. Then up-converts ...
Also unlike DVB, all DSS receivers are proprietary DirecTV reception units. DirecTV is now using a modified version of DVB-S2, the latest version of the DVB-S protocol, for HDTV services off the SPACEWAY-1, SPACEWAY-2, DirecTV-10 and DirecTV-11 [2] satellites; however, huge numbers of DSS encoded channels still remain. The ACM modulation scheme ...
Most Ethernet cables are wired straight-through (pin 1 to pin 1, pin 2 to pin 2, and so on). In some instances, the crossover form (receive to transmit and transmit to receive) may still be required. A cable for Ethernet may be wired to either the T568A or T568B termination standard at both ends of the cable. Since these standards differ only ...
A radio repeater is a combination of a radio receiver and a radio transmitter that receives a signal and retransmits it, so that two-way radio signals can cover longer distances. A repeater sited at a high elevation can allow two mobile stations, otherwise out of line-of-sight propagation range of each other, to communicate. [ 1 ]
