WebFor net propagation delay is the delay between the time a signal is first applied to the net and the time it reaches other devices connected to that net. Propagation delay is taken as the average of rise time and fall time i.e. Tpd= (Tphl+Tplh)/2. Propagation delay depends on the input transition time (slew rate) and the output load. WebPropagation delay is defined as the flight time of packets over the transmission link and is limited by the speed of light. For example, if the source and destination are in the same building at the distance of 200 m, the propagation delay will be ∼ 1 μsec. If they are located in different countries at a distance of 20,000 km, however, the ...
