propagation delay

[‚präp·ə′gā·shən di‚lā]
(electronics)
The time required for a signal to pass through a given complete operating circuit; it is generally of the order of nanoseconds, and is of extreme importance in computer circuits.

propagation delay

The time it takes to transmit a signal from one place to another. Propagation delay is dependent solely on distance and two thirds the speed of light. Signals going through a wire or fiber generally travel at two thirds the speed of light. Contrast with nodal processing delay.

Reducing the propagation delay will require reducing
where LP is the number of the multipath components and [mathematical expression not reproducible] and [[tau].sub.i,m] are the complex attenuation of the ith path and propagation delay of the ith path in mth antenna, respectively.
The detected synchronization point, p', allows us to compensate for the propagation delay in the estimated channel responses, hence centering the most powerful tap around [kappa] = 0.
So, it is the result of adding the transmission and propagation delay. In order to calculate the transmission time for the wired and wireless systems, we had to know the data rate and packet size of both systems.
Consolidated variations of propagation delay of different interconnect geometries are given in Table 2.
However, these schemes do not consider RTT-unfairness between the two competing flows which have different end-to-end propagation delay. A flow which has long end-to-end propagation delay shares less bandwidth than a flow that has short end-to-end propagation delay.
It was shown that this allows to state that the propagation delay from the proposed model is less than 5% for n higher than twenty cells.
Te paper illustrates the reference architecture template, the adder propagation delay model upon which the design method is built, the design procedure detailed description, the general validation of the approach, and a specific example with performance results referring to 32 ns CMOS technology and reporting speed and power data.
With a focus on reducing transceiver loop time (propagation delay through the transceiver) and the impact of the network on the loop time, these transceivers provide higher data rates and improved timing margin while using the standard CAN protocol layers such as CANopen and DeviceNet.
The ADuM3223 and ADuM4223 isolated half-bridge gate drivers feature sub 55ns propagation delay and less than 5ns delay matching.
The propagation velocity, conversely the propagation delay, [t.sub.pd] and critical length may be calculated as follows, where C is the speed of light and [D.sub.k] is the dielectric constant at the operating frequency:
If the propagation delay of the cable is known, then the distance to the short can be calculated using
