In telecommunications, receive-after-transmit time delay is the time interval between (a) the instant of keying off the local transmitter to stop transmitting and (b) the instant the local receiver output has increased to 90% of its steady-state value in response to an RF signal from another transmitter.
Roundtrip time = 2 × Packet delivery time + processing delay. In case of only one physical link, the above expression corresponds to: Link roundtrip time = 2 × packet transmission time + 2 × propagation delay + processing delay. If the response packet is very short, the link roundtrip time can be expressed as close to:
The time delay is usually measured in slots, which are fixed-length periods (or slices) of time on the network. In a binary exponential backoff algorithm (i.e. one where b = 2 ), after c collisions, each retransmission is delayed by a random number of slot times between 0 and 2 c − 1 .
The time-to-digital converter measures the time between a start event and a stop event. There is also a digital-to-time converter or delay generator. The delay generator converts a number to a time delay. When the delay generator gets a start pulse at its input, then it outputs a stop pulse after the specified delay.
Tay, Mareels and Moore (1998) defined settling time as "the time required for the response curve to reach and stay within a range of certain percentage (usually 5% or 2%) of the final value." [ 2 ] Mathematical detail
In telecommunications, attack-time delay is the time needed for a receiver or transmitter to respond to an incoming signal.. For a receiver, the attack-time delay is defined as the time interval from the instant a step radio-frequency signal, at a level equal to the receiver's threshold of sensitivity, is applied to the receiver input, to the instant when the receiver's output amplitude ...
In telecommunications, transmit-after-receive time delay is the time interval from removal of RF energy at the local receiver input until the local transmitter is automatically keyed on and the transmitted RF signal amplitude has increased to 90% of its steady-state value.
In telecommunications, round-trip delay (RTD) or round-trip time (RTT) is the amount of time it takes for a signal to be sent plus the amount of time it takes for acknowledgement of that signal having been received. This time delay includes propagation times for the paths between the two communication endpoints. [1]
