duplex system การใช้

• In full-duplex systems, keystrokes are transmitted one by one.
• In half-duplex systems, keystrokes are echoed locally on a computer terminal.
• Duplex systems can be divided into two types.
• A good analogy for a full-duplex system is a two-lane road with one lane for each direction.
• The installations were configured as duplex systems, using a pair of AN / FSQ-7 computers to provide fault tolerance.
• Half-duplex systems are usually used to conserve bandwidth, since only a single communication channel is needed, which is shared alternately between the two directions.
• Two-way radios can be designed as full-duplex systems, transmitting on one frequency and receiving on another; this is also called frequency-division duplex.
• Frequency-division duplex systems can extend their range by using sets of simple repeater stations because the communications transmitted on any single frequency always travel in the same direction.
• In automatically run communications systems, such as two-way data-links, the time allocations for communications in a half-duplex system can be firmly controlled by the hardware.
• A good analogy for a half-duplex system would be a one-lane road with traffic controllers at each end, such as a two-lane bridge under re-construction.
• This could be acquired in time division duplex systems by assuming the channel from the transmitter to the rate of transmission, and / or bit error rates, by exploiting the channel state information that is present at the transmitter.
• In the duplex system one engine actuated the steam valves of the other, and a pause of the pistons at the end of the stroke permitted the water-valves to seat themselves quietly and preserve a uniform water pressure.
• The major clinical indications for this investigation are the detection and / or evaluation of a renal scar, the small or absent kidney ( renal agenesis ), an occult duplex system, certain renal masses, systemic hypertension or suspected vasculitis.
• Duplex systems are employed in many communications networks, either to allow for a communication " two-way street " between two connected parties or to provide a " reverse path " for the monitoring and remote adjustment of equipment in the field.
• The whole duplex system required many seven foot frames of circuit packs plus at least one tape drive frame ( most telephone companies wrote billing data on magnetic tapes ), and many washing machine sized ( and look with the open top door ) disk drives.
• A "'duplex "'communication system is a plex " that means " structure " or " parts of "; thus, a duplex system has two clearly defined data transmissions, with each path carrying information in only one direction : A to B over one path, and B to A over the other.
• An example of a half-duplex system is a two-party system such as a walkie-talkie, wherein one must use " over " or another previously designated keyword to indicate the end of transmission, and ensure that only one party transmits at a time, because both parties transmit and receive on the same frequency.
